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 MOC'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.
