General Purpose
The WJA1015 consists of Darlington pair amplifiers using
a high reliability InGaP/GaAs HBT process technology.
The MMIC amplifier is internally matched to 50鈩?and only
requires DC-blocking capacitors and an inductive RF choke
for operation. An internal active bias is designed to enable
stable performance over temperature. It also eliminates the
need for a dropping bias resistor and allows the device to
be biased directly from a +5V supply voltage.
The amplifier is targeted for high performance RF applications
in existing and next generation wireless technologies. In
addition, the WJA1015 will work for various other
applications within the 50 to 4000 MHz frequency range.
