TC1950 PRE.1_06/21/2006 Preliminary 14 – 18 GHz LNA MMIC PHOTO ENLARGEMENT FEATURES • P1dB: 15 dBm • Noise Figure: 3 dB • Small Signal Gain: 19 dB • Bias Condition: 80 mA @ 5 V DESCRIPTION The TC1950 is a three stages PHEMT low noise amplifier MMIC that operates from 14 to 18 GHz. The amplifier provides a typical 19 dB of gain with 3 dB of noise figure and delivers 15 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.
