Robust 1000V ESD, Class 1C
Lead-free/green/RoHS-compliant
SOT-89 package
+5V Active-Bias InGaP HBT Gain Block
Product Description
The WJA1001 is a cascadable gain block that offers high
linearity in a low-cost surface-mount package. At 900 MHz,
the WJA1001 typically provides 19 dB gain, +45 dBm OIP3,
and +20 dBm P1dB. The device is housed in a lead-
free/green/RoHS-compliant SOT-89 SMT package using a
NiPdAu plating to eliminate the possibility of tin whiskering.
The WJA1001 consists of a Darlington-pair amplifier using
a high reliability InGaP/GaAs HBT process technology.
The amplifier has been optimized internally to offer very
high linearity performance at 1 GHz while drawing very
low current. The MMIC amplifier is internally matched to
50鈩?/div>
and only requires DC-blocking
capacitors and a bias
inductor for operation. An internal active bias is designed
to enable stable performance over temperature and allow
for operation 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
WJA1001 is ideal for general purpose applications such as
LO buffering or amplification and pre-driver stages within
the 50 to 3000 MHz frequency range.
