SOT-89 Packaging
The WJA1500 is a cascaded gain block that provides high linearity in a low cost surface mount package
At 200MHz, the WJA1500 typically provides 19.5dB gain, +43.5dB OIP3 and +20.5dB P1DB. The device is housed in a RoHS compliant SOT-89 industry standard SMT package with annealed matt tin or Nippau plating to reduce or eliminate the possibility of tin whiskers.
The WJA1500 consists of Darlington pair amplifiers using high reliability INGAP/GAAS HBT process technology. The MMIC amplifier is internally matched to 50Ω and requires only DC blocking capacitors and bias inductors to work. Internal active bias is designed to achieve stable performance over temperature. A falling bias resistor is not required, allowing the device to be biased directly from the +5 V supply voltage.

The amplifier is targeted for high-performance mid-frequency applications in existing and next-generation wireless technologies. The WJA1500 is ideal for general purpose applications in the 50 to 1000 MHz frequency range such as low buffering, mid-frequency amplification and pre-drivers
The pin number label describes the RF input, matched to 50 ohms. Requires external DC block.
RF output RF output/DC power supply, matching 50 ohms. Requires external DC block, RF choke.

notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Terminal 1 identifiers and terminal numbers are in accordance with JESD 95-1 SPP-012.
3. Up to 4-digit tracking code notes assigned by subcontractors:
2. Use at least 1 oz copper for top and bottom metal.
3. Through holes are required under the rear bezel of this device to ensure proper RF/DC grounding and thermal conductivity.
4. Do not remove or minimize through-hole structures in the PCB. Thermal grounding and RF grounding are critical.
5. We recommend drilling with a 0.35mm (80/.0135”) diameter drill bit for a final plating diameter of 0.25 mm (0.10”).
6. Ensure good package back bezel solder connection for reliable operation and best electrical performance.
