CMA-81+
+RoHS Compliant
The +Suffix identifies RoHS Compliance. See our web site
for RoHS Compliance methodologies and qualifications
General Description
CMA-81+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It uses patented Tran-
sient Protection Darlington configuration and is fabricated using InGaP HBT technology. The MMIC am-
plifier is bonded to a multilayer integrated LTCC substrate and then hermetically sealed under a controlled
Nitrogen atmosphere with gold plated cover and eutectic Au-Sn solder. Terminal finish is Ni-Pd-Au. It
has repeatable lot to lot performance due to tightly controlled semiconductor and assembly processes.
These amplifiers have been qualified to MIL requirements and have been tested for hermeticity.

RF input pin. This pin requires the use of an external DC blocking capacitor chosen
for the frequency of operation.
RF output and bias pin. DC voltage is present on this pin; therefore a DC blocking

capacitor is necessary for proper operation. An RF choke is needed to feed DC
bias without loss of RF signal due to the bias connection, as shown in “Recom-
