Product Description
Functional Diagram
The WJA1500 is a high performance amplifier that offers
high linearity in a low-cost surface-mount package. At 200
MHz, the WJA1500 typically provides 20 dB gain, +43
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.
The WJA1500 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. Biased directly from a 5V supply, an internal
active bias network enables stable operation over
temperature, eliminating the need for the typical dropping
bias resistor.

The amplifier is targeted for high performance IF applications
in existing and next generation wireless technologies. In
addition, the WJA1500 will work for various other
applications within the 50 to 1000 MHz frequency range.

2. 3OIP measured with two tones at an output power of 0 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
