Teledyne e2v HiRel, part of the Teledyne Defense Electronics Group, has announced the availability of a family of 14 GHz RF gain blocks spearheaded by the TDGB014-003, an 18.4 dB amplifier. The Gain Blocks are based on an indium gallium phosphide (InGaP) technology that is suitable for use in aerospace and defense applications because of its ceramic packaging and space qualification.
These gain blocks are available in gain configurations of 13.6 dB and 16.5 dB which allow the design engineer to configure the amplifier based on the required signal gain without incurring unwanted parasitic effects.
With this new family of X-band Gain Blocks, Teledyne e2v HiRel customers now have a standard amplifier solution that covers L-band through X-band. This standard amplifier enables a reduction in the number of new qualified components required for flight programs and thereby simplifies the component procurement process.
The TDGB014-003 50-ohm gain block utilizes a mature and reliable heterojunction bipolar transistor (HBT), InGaP process and incorporates proprietary Monolithic Microwave Integrated Circuit (MMIC) design techniques. The process has space-flight heritage and has shown to be radiation tolerant to 100 krad, making it a viable choice for satellites and other high-altitude applications.

Teledyne e2v’s Hi-Rel X-band Gain Blocks offer excellent gain flatness and high P1dB. This Gain Block family is available now and is packaged in a 2-lead, ultra-small, hermetic, gullwing package. Both the wafer process technology and the package have space flight heritage.
