For compact 800 MHz transceiver applications, REC has designed a surface mount isolator operating between 758 – 803 MHz with a footprint of 0.394 square inch. The
isolator can handle up to 5W forward and 0.25W reverse over -10 to 80°C temperature range.
The HGM and HGV series Gunn Oscillators cover the range from 26.5—110 GHz. A wide
variety of designs provide the user with a solution for most applications. Units are
available with mechanical and/or electrical tuning, providing many possible tuning
configurations. Superior frequency and power stability are achieved using cavity design and diode selection. Heaters can be provided to achieve greater frequency stability.
GaAs and InP Gunns are used depending on the frequency and performance requirements. Cavity designs are mated with the proper Gunn diode to maximize performance.
Gunn oscillators are used as sources for mixer LO’s, to drive multipliers, transmitters, and radars. Options include voltage regulators, heaters, isolators, heat sinks, and micrometer tuners.
Series HGM/HGV Datasheet
HXI’s HMID series of double ferrite junction isolators are available to cover 71-76 GHz and 81-86 GHz, with more models planned. The isolators utilize a low loss H-plane structure in a modified Y-junction format to provide minimum loss with high isolation (~40 dB).
The isolators are commonly utilized to buffer mismatches and are often used on amplifier and oscillator outputs. They also work nicely when used at the inputs to detectors in measurement applications.

Renaissance has designed a high power UHF-band 2:1 combiner for use in communication systems, instrumentation applications and military mobile devices. This 470 – 860 MHz combiner features low amplitude and phase balance, along with a power input of 330 Watts per channel.
Renaissance has designed two drop-in circulators (UHF/Broadband) designed for CW and pulsed applications such as wireless infrastructures, RADAR, Military communication radios and duplexing applications. Operating over 500 – 900 MHz and 690 to 1100 MHz respectively, these circulators are compact in size (~ 2” x 2” x 0.6”) and are capable of withstanding 350W of CW power levels.
To improve VSWR at the antenna port on a downconverter for satcom applications, REC has designed a 28 – 30 GHz drop-in isolator with low loss performance operating over -40°C to +85°C temperature range.
Renaissance has developed a new drop-in isolator to suppress mismatches in the receiver circuits at VHF band frequencies. Covering 420 – 450 MHz, this isolator provides a VSWR of 1.35:1 at input and output ports with loss of 0.7 dB and isolation of 18 dB over -40 to +85 C.
