50 W Broadband Power Amplifier
This high performance 50 W RF power amplifier covers a broad frequency range from 500 to 1000 MHz. The amplifier is available as a 28 V DC module and features a gain of 30 dB (typ). The unit is also available as a full AC system with automatic current limiting, forced-air cooling, current meter, and overcurrent and thermal protection. Size: 6.0" x 3.5" x 1.4". Weight: less than 1.5 lbs.
8 W Three-carrier CDMA Power Amplifier
The model HPA8689-8-2K power amplifier covers the entire cellular transmit band of 869 to 894 MHz with an average total power level of 8 W with three CDMA carriers. Designed for single-channel repeaters, microcells and tower-top applications or CDMA 2000 requirements, the amplifier operates over a DC input range of 25 to 30 V DC and a baseplate temperature range of 0° to 65°C. A TTL output is provided for major fault status, and circulator protection is provided for transmission into any load mismatch. Size: 9.55" x 11.60" x 1.12".
