  • Public Safety and Critical Communications

    There are many challenges faced by Public Safety networks. Their coverage and capacity are limited by buildings’ physical characteristics, interoperability with other wireless networks, mobile radio technology used (e.g., FMN, OpenSky, TETRA and APCO P25), and overall Passive Intermodulation (PIM) performance. Microlab offers a wide variety of reliable RF passive components suited for in-building wireless communication for emergency service personnel. Our trusted products help provide full coverage and increase capacity across independent and/or coexistent mobile radio and cellular networks.

  • Low PIM Terminations/Loads

    Microlab offers 698 – 2700 MHz low PIM terminations from 5W to 200W in convenient moisture sealed packages, similar to those used in conventional resistive attenuators and loads. A frequent application is terminating the load port of a hybrid combiner when adding two RF signals at a radio base station, so an integrated package of hybrid and low PIM load is also offered.

  • Directional Couplers

    Directional couplers provide flat coupling of one signal path to another in one direction only (known as directivity) and low VSWR over one full octave or more. They commonly consist of an auxiliary line coupling electrically to a main line, which becomes more complex as the bandwidth increases. One end of the auxiliary line is permanently fitted with a matched termination. Directivity (the difference between coupling in one direction compared to the other) is approximately 20 dB for printed couplers, 25 dB or more for air-dielectric couplers. Directional couplers are used whenever part of a signal needs to be separated off or two signals need to be combined. Microlab offers narrow band and wireless band directional couplers with coupling ranging from 3 dB to 50 dB or more, always reference to the input port.

    Directional Couplers
  • Wilkinson power Splitters

    Wilkinson dividers/splitters offered in 2, 3, 4, 6 and 8 ways are most commonly designed on microstrip boards in convenient packaging. They have outputs which are isolated by 20 dB or more, but are generally limited to low power applications because the resistors used in such designs are usually less than 1W. The resistors also cause poor PIM performance so Wilkinson dividers/splitters should not be used when low PIM is a requirement. Microlab offers wireless designs with bands extending from Tetra and P-25 frequencies to 6 GHz.

    Wilkinson power Splitters
  • Reactive Power Splitters

    Reactive splitters offered in 2, 3, 4, and 6 ways, use air-line dielectrics with silver plated, metal conductors in aluminum housings. They have excellent input VSWR, high power ratings, low PIM and very low losses usually 0.05 dB or less. Modern design techniques allow bandwidths that extend from 380 to 4200 MHz in housing of convenient length. Reactive splitters are frequently employed in in-building systems because they are virtually indestructible, low loss and low PIM.

    Available with in-line or opposed connectors.

    Reactive Power Splitters
  • DC Blocks

    Microlab DC Blocks are used to prevent the flow of direct current and low frequency current surges along the inner and/or the outer conductors of a transmission line, while permitting the unimpeded flow of RF signals. Applications include the blocking of current surges that can occur in subway tunnels and rail systems, at base-station/cell-sites during lightening storms, to route DC to tower mounted amplifiers (TMA’s) or whenever DC isolation is required. Units are available with a DC block on the inner and/or outer conductor, and all units are built with special attention to effects of PIM.

    DC Blocks
  • In-Building Antennas

  • Low PIM Jumper Cables

    Whether macro cells or in Building DAS venues, the wrong RF cable can have a devastating influence on network reliability and quality of service. Passive intermodulation (PIM) is often thought “negligible” at in-building DAS venues, but this is not the case. The front end of a DAS Carrier Combiner interface is particularly susceptible to PIM interference. High power levels are attenuated and combined at this stage. If PIM levels are not minimized the system’s overall performance is reduced significantly. Our new J-cables are especially designed with these requirements in mind. They are 100% tested to guarantee the best system performance.

    Microlab Model JA and JB series, Coaxial Jumper Cables are built for consistent low PIM performance. Designed for use in all systems where low PIM and excellent electrical performance and mechanical reliability are paramount. With an operating range of DC to 6 GHz, these cables are ideal for all telecommunication applicatio...

  • Low PIM Attenuators

    Microlab FY Series is a low PIM, unidirectional Attenuator, using a multi section, quarter wave, stripline coupler with a low PIM cable load. It is designed for indoor applications covering all wireless bands from 694 to 2,700 MHz. This model couples off a portion of the input power to the output. This achieves a flat attenuation response over a wide frequency range, 617-2700MHz.
    The wide frequency range allows use with multiband antennas and leaky cable systems and in wireless base stations. With minimal solder joints and an air dielectric, the dissipative loss has been minimized and reliability enhanced.

  • Low PIM Tappers

    Microlab Tappers unevenly split high power cellular signals in fixed ratios from 1000:1 to 2:1 with minimal reflections or loss over the key wireless bands in the range 350 - 5,930 MHz, (there is no coupling 1550 to 1650 MHz). The innovative asymmetric design ensures an excellent input VSWR and coupling flatness across the specified bands, even down to a 2:1 split.

    The lightweight design allows easy attachment to a wall using the supplied bracket. Designed with only a few solder joints and an air dielectric, loss is minimized and reliability enhanced.

    Available in 7/16 DIN, N, and 4.3-10 connectors.

  • Hybrid Couplers/Combiners

    Hybrid Couplers have the important characteristic that allows addition of two or more signals without interaction regardless of how close the frequencies of the signals may be. This feature can often eliminate the need for filters which can often introduce signal aberrations. Microlab’s Hybrid Couplers have ultra wide bandwidths, very low PIM and minimal loss. The most commonly recommended hybrid for wireless systems is a multisection, stripline design, covering 700 MHz to 2700 MHz, which includes the present and future cellular, PCS, 3G and 3G/4G extension bands. Other units extend frequency coverage with flat response from 350 MHz to 6000 MHz, but at the cost of greater size and weight.

    Microlab has models specifically designed for use in harsh outdoor environments.

    Microlab's hybrid's offer the highest isolation in the industry, and are offered in :

    Standard bandwidth 617-2700MHZ.

    Ultra-wideband 350-5925MHz.
