The WJA1025 is a cascadable gain block that offers high
linearity in a low-cost surface-mount package. At 1.9 GHz,
the WJA1025 typically provides 17 dB gain, +32 dBm
OIP3, and +15.5 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 WJA1025 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
WJA1025 is ideal for general purpose applications such as
LO buffering, IF amplification and pre-driver stages within
the 50 to 4000 MHz frequency range.

1. Test conditions: 25 ºC, Supply Voltage = +5 V, 50 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 2 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
