DESCRIPTION
The TC1954 is a two stages PHEMT high power amplifier MMIC that operates from 14 to 18 GHz. The
amplifier provides a typical 10 dB of gain and delivers 33 dBm of P
1dB
. The MMIC is fabricated using
Transcom’s proprietary matured GaAs PHEMT process. The process features full passivation for
increased performance and reliability. All devices are 100 % DC tested to assure consistent quality. Bond
pads are gold plated for either thermocompression or thermosonic wire bonding. Backside gold plating is
compatible with standard AuSn die-attach.
