FM Pallet 350watts SD2942
Designed for FM transmitters, this amplifier incorporates microstrip technology and an SD2942 MOSFET transistor to enhance ruggedness and reliability. 86-110MHz 48 Volts SD2942 MOSFET Input/Output 50 ohms Pout 350W min. w/4 watt input. 20% higher power saturation than SD2932, MRF151G and BLF278 18 dB gain minimum. Low distortion Class B push-pull. Temperature compensated bias Compact size; LxWxH 4.0 x 2.0 x 1.5 inches Standard 1/4 inch copper heat spreader. The SD2942 mosfet is new technology that was recently introduced by ST. This is the first VHF 48V push-pull mosfet with a 350W factory power rating. Our PA's use teflon low impedance high temperature coax to form high power matching transformers.

Designed for FM transmitters, this pallet amplifier incorporates broadband matching and a MRF173 MOSFET transistor. 86 – 110MHz. 28 Volts. Input/output 50 ohms. Pout: 80W 18dB Gain (80W) Class AB. Requires 28Vdc at 4.0 amps typical. No bias adjustments or RF circuit tuning is required.
The SD2941-10 is the latest technology from ST Microelectronics. This new design incorporates a 4:1 broadband coaxial transformer matching scheme. The result is high efficiency and improved frequency response. Diode temperature compensated bias for enhanced performance over temperature. New bias disable pads facilitate integration into amplifier systems that employ automatic VSWR protection. Taking this pad to ground will shut down the amplifier.
