The WJA1015 is a cascadable gain block that offers high
linearity in a low-cost surface-mount package.
MHz, the WJA1015 typically provides 15 dB gain, +37
dBm OIP3, and +17 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 WJA1000 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 a +5V supply voltage.
The broadband amplifier can be directly applied to various
current and next generation wireless technologies such as
GSM, PCS, and W-CDMA. The WJA1015 is ideal for
general purpose applications such as LO buffering, IF
amplification and pre-driver stages within the 50 to 2300
MHz frequency range.
