Product Description
The WJA1010 is a high performance amplifier that offers
high linearity in a low-cost surface-mount package. At 900
MHz, the WJA1010 typically provides 14 dB gain, +40
dBm OIP3, and +20 dBm P1dB. The device is housed in a
lead-free/green/RoHS-compliant SOT-89 industry-standard
SMT package using a NiPdAu plating to eliminate the
possibility of tin whiskering.

General Purpose
The WJA1010 consists of Darlington pair amplifiers using
a high reliability InGaP/GaAs HBT process technology.
The MMIC amplifier is internally matched to 50Ω 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 WJA1010 will work for various other
applications within the 50 to 4000 MHz frequency range.
