Product Description
The WJA1030 is a cascadable gain block that offers high
linearity in a low-cost surface-mount package. At 1.9 GHz,
the WJA1030 typically provides 15 dB gain, +37 dBm
OIP3, and +18 dBm P1dB. The device is housed in a
RoHS-compliant SOT-89 industry-standard SMT package
using a NiPdAu plating to eliminate the possibility of tin
whiskering.

0.2dB gain flatness from 0.3-2.5GHz The WJA1030 consists of Darlington pair amplifiers using
a high reliability InGaP/GaAs HBT process technology.
Robust 1000V ESD, Class 1C
The MMIC amplifier is internally matched to 50 and only
RoHS-compliant SOT-89 package
requires DC-blocking capacitors and a bias inductor for
operation. An internal active bias is designed to enable
stable performance over temperature. A dropping bias
resistor is not required allowing the device to be biased

The broadband amplifier can be directly applied to various
current and next generation wireless technologies such as
GSM, CDMA, W-CDMA, WiBro, and WiMAX. The
WJA1030 is ideal for general purpose applications such as
LO buffering, IF amplification and pre-driver stages within
the 50 to 4000 MHz frequency range.
