GaAs MMIC
Power Amplifier
DESCRIPTION
AMCOM’s AM08011039WM-00 (SN-R) is a broadband GaAs MMIC power amplifier. It has 25dB small signal gain,
and >40dBm output power over the 8 to 11GHz band at 8V bias. The AM08011039WM-00 is an un-packaged bare
die. Because of high DC power dissipation, we strongly recommend to mount these devices with eutectic bonding
directly on a copper heat sink. It is capable of working at 8V DC bias voltage under pulsed condition if the eutectic
bonding does not have any voids. Otherwise, we recommend operating the MMIC at 7V DC bias to provide some
thermal margin. The AM08011039WM-SN-R is in a ceramic package with a flange and straight RF and DC leads for
drop-in applications. Good heat sinking is required. Both chip and packaged versions are RoHS compliant.

Current may change from lot to lot. Adjust Vgs to reach Idsq1=300mA, Idsq2=1.2A, Idsq3=2.4A. Vds of 8V is at the
MMIC drain terminal. Because Ids is around 4 Amp, if your test system has a 0.1-ohm resistance between the DC
power supply and the MMIC drain, it will have a drop of 0.4V, which reduces output power. In this case, we
recommend raising the DC power supply voltage to 8.4V.
*** Power data are pulsed results for 5% pulse duty cycle and 1mS pulse width.

CHIP TEST FIXTURE
Important Notes:
1- Recommended current biases are 0.3A , 1.2A and 2.4A for the first stage , second and third stage
respectively. Gate bias of -1.8V is for reference only. Vgg could be adjusted to vary the currents going thru
the MMIC.
2- Do not apply Vds1 &, V ds2 & Vds3 without proper negative voltages.
3- The currents flowing out of the two Vgg pins are around 300mA.
