TC1954 PRE.1_06/21/2006 Preliminary 14 – 18 GHz 2W PA MMIC FEATURES PHOTO ENLARGEMENT • P1dB: 33 dBm • Small Signal Gain: 10 dB • Bias Condition: 1400 mA @ 8 V 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 P1dB. 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.
