HMC608LC4
v03.0514
GaAs pHEMT MEDIUM
POWER AMPLIFIER, 9.5 - 11.5 GHz
General Description
Features
Functional Diagram
The HMC608LC4 is a high dynamic range GaAs
pHEMT MMIC Medium Power Amplier housed in a
leadless “Pb free” SMT package. The amplier has
two modes of operation: high gain mode (Vpd pin
shorted to ground); and low gain mode (Vpd pin left
open). The electrical specications in the table below
are shown for the amplier operating in high gain
mode. Operating from 9.5 to 11.5 GHz, the amplier
provides 29.5 dB of gain, +27.5 dBm of saturated
power and 23% PAE from a +5V supply voltage.
Noise gure is 6 dB while output IP3 is +33 dBm. The
RF I/Os are DC blocked and matched to 50 Ohms
for ease of use. The HMC608LC4 eliminates the
need for wire bonding, allowing use of surface mount
manufacturing techniques.
Output IP3: +33 dBm
Saturated Power: +27.5 dBm @ 23% PAE
Gain: 29.5 dB
Supply: +5V @ 310 mA
