| TC4535 PRE1_12/12/2004 Preliminary 13.75 - 14.5 GHz 1W MMIC FEATURES * * * * * P-1 dB: 30 dBm Small Signal Gain: 30 dB IP3: 39 dBm Match to 50 Operation Bias condition:750 mA @ 8 V DESCRIPTION The TC4535 is a 4 stage PHEMT MMIC power amplifier. It is designed for use in low cost, high volume, Ku band applications. The MMIC is matched to 50ohm operation. No external matching component is required. It provides a typical gain of 30 dB and P1 dB power of more than 29 dBm. Typical bias condition is 8V at 750 mA. The MMIC is a packaged in a copper based ceramic 6 pins power package. The copper based carrier of the package allows direct soldering of the device to the PCB for proper heat sinking.
