Description

M/A-COM’s AM52-0024 is a 0.5 W, 2.4 GHz GaAs
MMIC, power amplifier in a low-cost MSOP-8 package. It
employs some external matching to obtain optimum input
return loss and output power performance. The AM52­0024 may be operated with supply voltages of +3.3 V to
+5.5 V.

The AM52-0024 may be used in a wide variety of applic a­tions including WLAN, WDECT, and Bluetooth.

The AM52-0024 is fabricated using M/A-COM’s Self­Aligned MSAG MESFET process to realize high power
efficiency, single supply voltage, and small size. The proc­ess features full passivation for increased performance and
reliability.

Designing With the AM52- 0024

The AM52-0024 is built using a near -enhancement mode FET that operates from a single supply voltage. A negative
voltage is not required because the FET is designed to operate with a +0V DC gate bias.

To duplicate AM52-0024 data sheet performance, the circuit board must present the same impedances realized on
this evaluation board. The table below has impedance measurements looking into the traces on the evaluation board,
