Targeting the receive side requirements for a low loss waveguide isolator, Renaissance has developed a product with less than 0.2 dB insertion loss over 20.1 to 21.2 GHz from -40 to +85 C. Ensuring more than 26 dB isolation, the unit improves system performance considerably. With a size of 1.5" x 0.88" x 0.5", it can handle up to 50 W of forward and 5 W of reverse power.

The HMC10H and HMI10H series High Power Circulators and Isolators operate in the 75 to 110 GHz waveguide band. They handle up to 20 W of average power and 350 W peak. A RF bandwidth of 2 to 3 GHz and isolation of 18 dB are typical. These devices are used to buffer mismatches, signal duplexers, and to couple amplifier stages.

The HHPAW-441 is a W-Band pulsed high power amplifier that offers +27 dBm (½ W) of RF power over the range from 92 to 96 GHz. This amp can be operated with a variable pulse rate from CW to 100 nS. The amplifier uses the latest MMICs that are power combined for the maximum RF power and gain.

The HLNAV-360 is a low noise amplifier with integrated isolators at the input and output ports. The LNA operates over the 57 to 64 GHz frequency band with 27 dB gain, noise figure of 6.0 Db and a P1dB of +12 dBm. RF interfaces are via WR-15 waveguide with standard UG-385/U flanges.

The HHPAV-433 Power Amplifier covers the frequency range from 59.5 to 60.5 GHz and is usable over the range of 58 to 64 GHz. The amplifier has an output power of +28.5 Psat and 18 dB gain.  A single +6.0V bias is used to power up the amplifier.

Renaissance Electronics has designed an in-band duplexer for LTE cell site applications. In a very compact footprint of 4.75” x 3.15”, the duplexer provides 30 dB of rejection between the Tx and Rx. The insertion loss is less than 1 dB.

The 15C2NX is the RF interface DAS panel that duplexes the BTS port for Rx/UL and Tx/DL channels with the help of a circulator.The power levels on the UL and DL can be adjusted by the use of fixed and manual rotary attenuators. The minimum isolation between channels is 50 dB and with insertion loss of less than 2 dB in the through paths.

This newly designed dual 48 x 4 switch matrix for ATE applications can cover from 700 MHz (LTE) to 6 GHz (Wi-Fi) frequencies. Using high reliability solid state switches, the switching speed is on the order of nanoseconds helping test handsets and other portable communication devices with minimum delay time.
