General Description
Features
Functional Diagram
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.
Output IP3: +33 dBm
Saturated Power: +27.5 dBm @ 23% PAE
Gain: 29.5 dB
Supply: +5V @ 310 mA
50 Ohm Matched Input/Output
RoHS Compliant 4x4 mm SMT Package
Electrical Specifications, TA = +25° C, Vdd1, 2, 3 = 5V, Idd = 310 mA [1], Vpd = GND [2]
Typical Applications
The HMC608LC4 is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Military End-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.

List of Materials for Evaluation PCB 112763 [1]
The circuit board used in this application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation board should be mounted to an appro-
priate heat sink. The evaluation circuit board shown
is available from Analog Devices upon request.
