Functional Diagram
General Description
The HMC608LC4 is a high dynamic range GaAs
PHEMT MMIC Medium Power Amplifier housed in a
leadless “Pb free” SMT package. 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 29.5 dB of gain, +27.5 dBm of saturated
power and 23% PAE from a +5V supply voltage.
Noise figure 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.
Electrical Specifications, TA = +25° C, Vdd1, 2, 3 = 5V, Idd = 310 mA [1], Vpd = GND [2]
