| TC4541 REV.2_04/12/2004 13.75 - 14.5 GHz 2W MMIC FEATURES * * * * P-1 dB: 33 dBm Small Signal Gain: 26 dB IP3: 42 dBm Bias Condition: 1500 mA @ 8 V PHOTO ENLARGEMENT DESCRIPTION The TC4541 is a four stage PHEMT power amplifier MMIC that is designed for use as an output stage or a driver in VSAT ODU. The amplifier provides 26 dB gain and delivers 2 watt output power from 13.75 to 14.5 GHz. The small package provides a simple, cost effective solution to customized designs. The metal base carrier provides excellent thermal dissipation for the internal MMIC dies. The MMIC is fabricated using a mature GaAs PHEMT process. The process features full passivation for increased performance and reliability. It is 100% RF tested to ensure compliance to performance specifications.
