Description
The P35-4780-C06 is a high performance GaAs MMIC containing a two stage Tx power amplifier and a
Tx/Rx diversity switch. This device is designed to complement the P35-4712/3 wireless transceiver MMICs
in applications requiring linear power amplification. Thus it is primarily intended for wireless applications
in the 2.4 to 2.5GHz ISM band but it can also be used for other applications in the 1.7-3GHz frequency range
where high gain and power are required.
The power amplifier requires positive and negative power supplies (nominally
鹵5V).
The switch is
controlled by the application of complimentary 0V/-5V signals to the control lines in accordance with the
truth table below.
This die is fabricated using MCL's 0.5碌m gate length MESFET process (S20) and is fully protected using
Silicon Nitride passivation for excellent performance and reliability. This device is packaged in a SO8 sized
surface mount ceramic package.
