Renaissance Electronics has developed a low loss, high isolation waveguide isolator for Satcom applications that covers 43 – 46 GHz with industry standard interface of WR 22. With loss of 0.5 dB and 18 dB isolation, it is ideal for low noise figure Satcom receivers.
Renaissance has released an S-band 2.5 kW peak power drop-in circulator operating from 2.9 to 3.3 GHz. With insertion loss of less than 0.6 dB and with return loss and isolation over 19 dB, the circulator is ideal to duplex an antenna with HPA and a receiver. This circulator has been customized to withstand 250 W of forward and 150 W of reverse power at the same instance without arcing or corona failures.
The HGM and HGV series Gunn Oscillators cover the range from 7 – 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.
HXI was instrumental in securing the FCC allocation of the 60 GHz digital radio spectrum in the USA, and we were the first FCC Part 15.255-certified MMW system operating in the 57 to 64 GHz band (V-Band).Since that time, HXI has consistently set the mark for reliability, capacity, and low cost of ownership for V-Band and E-band (70/80 GHz) digital radios. This tradition continues with our newest GigaLink Lightspeed Millimeter Wave radios, which are available to satisfy most regional allocation rules.

Renaissance’s latest Ku-band drop-in Isolator has been designed for use in satellite communication applications, including direct broadcast satellite for satellite TV, and
backhauls. This isolator has typical isolation of 20 dB and 0.5 dB loss over 13.75 – 14.5 GHz.
HXI’s HMPA and HHPA Series of Power Amplifiers cover the frequency range from 18 – 100 GHz. A wide variety of gain and bandwidth combinations are available to provide the designer with a solution for most applications. Custom designs are available and in most cases, NRE is not required. MMIC technology is employed for high reliability and repeatability.
The amplifiers can be used in transmitters for communication and radar systems and also as gain blocks in LO chains and test equipment. Multiple devices can be combined to increase output power where necessary. For example, several watts of power have been obtained at 35 GHz. The amplifiers can also be packaged with other components for custom configurations.
Each power amplifier contains a voltage regulator and bias sequencing circuitry allowing the use of a single bias to power the amplifier.
Series HMPA/HHPA Datasheet
HXI has provided a number of customers with components in the 76 to 81 GHz range in support of the development and testing of automotive IC’s and modules. Among these components are integrated mixer/multipliers, LNA’s, power amplifiers and isolators. Both WR12 and WR-10 waveguide sizes are supported.
The integrated mixer/multiplier modules exhibit the same low conversion loss as our standalone HBM12 mixers and incorporate the same multiplier circuits as our standalone active frequency multipliers. The result is the same great conversion loss and flatness with the added benefits of smaller size and a lower price than buying two separate components.
