2.4 , 2.5GHz RF power amplifier using PM2107 IC

Using the PM2107 IC can be implemented a very simple and GaAs RFIC power amplifier for
applications in the 2400 MHz ISM band. This two stage RFIC amplifier is off-chip matched to provide optimum performance for a variety of applications. Operating from a 5 volt supply, the PM2107 can produce 1 watt of saturated output power with 45% typical efficiency.
Pins 2, 4, 7, and 9 are all “RF-hot,” and require matching networks or bypass circuits as shown in the schematic above.

A maximum FR4 board thickness of 18 mils is recommended to minimize via and trace inductances. Large value bypass capacitors shown (1000 pF and greater) need not be located close to the PM2107, but must be present in the circuit to insure low frequency stability. R3 and R4 improve inband stability, and R1 and R2 provide out-of-band stability.
The area beneath the amplifier and the associated matching networks must have a continuous ground plane. The fused lead pins 3 and 8 provide a low inductance source ground for the 2nd stage of the PM2107.
The inductance to the microstrip ground plane should be as low as possible in grounding these pins. Pin 1 should be grounded through a transmission line to achieve the required input match and improve inband stability. The other ground pins (5, 6, 10) should also be connected to ground through a low inductance path.

A lossy input match is formed by TRL1, TRL2, C8, and R3. TRL2 provides ground isolation between the two stages to improve stability. The output matching network consists of TRL3, C1, and C2.
