Product Description
The WJA1021 is a cascadable gain block that offers high
linearity in a low-cost surface-mount package. At 1.9 GHz,
the WJA1021 typically provides 17.5 dB gain, +37.5 dBm
OIP3, and +19 dBm P1dB. The device is housed in a lead-
free/green/RoHS-compliant
industry-standard
SOT-89
SMT package using a NiPdAu plating to eliminate the
possibility of tin whiskering.
The WJA1021 consists of 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 1.9 GHz while drawing very
low current. The MMIC amplifier is internally matched to
50 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
WJA1021 is ideal for general purpose applications such as
LO buffering or amplification and pre-driver stages within
the 50 to 4000 MHz frequency range.

Ω System. S-parameters and 3OIP measured at
device pins. All other specifications measured on evaluation board.
2. 3OIP measured with two tones at an output power of 3 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
