Product Description
Functional Diagram
The WJA1000 is a high performance amplifier that offers
high linearity in a low-cost surface-mount package. At 900
MHz, the WJA1000 typically provides 19 dB gain, +37
dBm OIP3, and +19.5 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 WJA1000 consists of Darlington pair amplifiers using
a high reliability InGaP/GaAs HBT process technology.
The MMIC amplifier is internally matched to 50and 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 WJA1000 will work for various other
applications within the 50 to 4000 MHz frequency range.

1. Test conditions: 25 ºC, Supply Voltage = +5 V, 50 Ω System.
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.
