Product Description
Functional Diagram
The WJA1035 is a cascadable gain block that offers high
linearity in a low-cost surface-mount package. At 1.9 GHz,
the WJA1035 typically provides 15 dB gain, +36 dBm
OIP3, and +16 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 WJA1035 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 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
directly from a +5V supply voltage.

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
WJA1035 is ideal for general purpose applications such as
LO buffering, IF amplification and pre-driver stages within
the 50 to 4000 MHz frequency range.
