Functional Diagram
General Description
The HMC608 is a high dynamic range GaAs PHEMT
MMIC Medium Power Amplifier chip. The amplifier
has two modes of operation: high gain mode (Vpd pin
shorted to ground); and low gain mode (Vpd pin left
open). The electrical specifications in the table below
are shown for the amplifier operating in high gain
mode. Operating from 9.5 to 11.5 GHz, the amplifier
provides 32 dB of gain, +27.5 dBm of saturated power
and 23% PAE from a +5V supply voltage. Noise
figure is 5.5 dB while output IP3 is +33 dBm. The RF
I/Os are DC blocked and matched to 50 Ohms for
ease of use.

[1] Adjust Vgg between -3 to 0V to achieve Idd = 310 mA typical.
[2] Vpd= ground for high gain mode, Vpd = open for low gain mode.
[3] In low gain mode, typical gain is 22 dB and typical current is 67 mA.
