Microwave Electronics’ line of unequal power splitters or tappers have been developed to unevenly split high power signals for in-building distributed antenna systems (DAS) applications & designs. They easily handle high power levels of 300 W (CW) and have an operational temperature range of -55° C to +85° C.

Richardson RFPD, Inc. announces immediate availability and full design support capabilities of a new Xinger® III 3 dB hybrid coupler from Anaren. The X3C17A1-03WS-CT is the latest addition to Anaren's Xinger III family of surface mount couplers and Doherty combiners designed especially for today’s higher power, more compact, and hotter-running equipment.

PMI Model CDT-2M18-30-BB Options DE, D is a threshold detector that operates over the 2 MHz to 18 GHz frequency range.  This model has a low insertion loss of 2.5 dB maximum and operates over an input power range of -30 to 0 dBm.  The threshold level is adjustable and the output signal is TTL positive logic.

Model LM-26G40G-14-20W-292MM is a high power limiter capable of withstanding an input power level of 20 W, 440 to 670 nsec pulse width, PRF 600 to 900 kHz, 40% duty cycle.  This model operates in the 26.5 to 40 GHz frequency range.  The insertion loss is 4.0 dB maximum, VSWR of 2.0:1 and 250 nsec response time and a typical leakage of +14 dBm.

Renaissance has produced a new low loss L-band high power drop-in circulator to protect PA's used in military radio transmitters.  Covering 1025 to 1095 MHz, this circulator has just 0.25 dB of insertion loss over -55 to +85 C while handling 1300 W peak at 1% duty cycle.

Renaissance has designed a Ka band microstrip isolator that can handle 2 W forward and reverse for satcom applications. With a compact 5 x 6 mm size, it provides low insertion loss in the forward direction and high isolation in the reverse direction.

Renaissance has designed a new dual junction circulator for LTE application that can operate from 700 to 915  MHz and provide over 50 dB isolation within the band. Aimed for Test and Measurement application, this device can handle 100 W with -150 dBc intermod products."

For the new EW and radar systems, Renaissance has designed a high performance circulator covering 1.25 to 1.40 GHz capable of handling 3 kW peak and 300 W average power levels. With low loss of 0.3 dB and isolation of 20 dB, it is optimized for airborne/flight applications.

PMI Model Number LM-30M3G-C3-1 is a high power limiter that operates from 30 MHz to 3.0 GHz. This limiter can handle input power levels up to 5 W CW and provides a maximum leakage of +10 dBm. The insertion loss is 1.2 dB maximum with a maximum VSWR of 1.5:1. The recovery time is less than 1 usec.

Renaissance has recently manufactured a 50 kW peak power circulator that can sustain 300 W CW operating at 775 to 920 MHz.  The input and output connectors are 7/8” EIA and the third port has a HN connector.
