Functional Diagram
General Description
The HMC308 & HMC308E are low cost MESFET
MMIC amplifiers that operate from a single +3 to
+5V supply from 0.8 to 3.8 GHz. The surface mount
SOT26 amplifier can be used as a broadband ampli-
fier stage or used with external matching for opti-
mized narrow band applications. With Vdd biased at
+5V, the HMC308 & HMC308E offers 18 dB of gain
and +20 dBm of saturated output power while requir-
ing only 53 mA of current. This amplifier is ideal as
a driver amplifier for transmitters or for use as a
local oscillator (LO) amplifier to increase drive levels
for passive mixers. The amplifier occupies 0.014 in
2
(9 mm
2
), making it ideal for compact radio designs.
