The WJA1510 is cascadable gain block that offers high
linearity in a low-cost surface-mount package.
MHz, the WJA1510 typically provides 14 dB gain, +47
dBm OIP3, and +20 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.
The WJA1510 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 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 +5V supply voltage.
The amplifier is targeted for high performance IF applications
in existing and next generation wireless technologies. The
WJA1510 is ideal for general purpose applications such as LO
buffering, IF amplifier and pre-driver stages within the 50 to
1000 MHz frequency range.
