AH1G

The AH1G from WJ Communications is a high dynamic range amplifier utilizing GaAs MMIC technology. It is designed for applications where high linearity is critical, making it suitable for both receiver and transmitter functions.

This amplifier operates within a broad frequency range of 250 to 4000 MHz. Key electrical specifications include a typical gain of 13.5 dB, an output P1dB of +22 dBm, and a high output IP3 of +41 dBm. The noise figure is a low 3 dB, contributing to its suitability for sensitive receiver applications. It requires a single +5 V supply and has an operating current range of 120-180 mA.

The AH1G is housed in an environmentally-friendly, lead-free, green, and RoHS-compliant SOT-89 surface-mount package. Its design combines dependable performance with high quality, aiming for Mean Time Between Failures (MTTF) exceeding 100 years at +85 °C mounting temperatures.

Applications for the AH1G include mobile infrastructure, CATV/DBS, W-LAN, Wi-Bro, WiMAX, RFID, defense, homeland security, and fixed wireless systems. It is well-suited for current and next-generation wireless technologies such as GPRS, GSM, CDMA, and W-CDMA.
