FM wideband amplifier, with microstrip technology and BLF369 RF mosfet.
LBF369 was introduced recently and makes this amplifier possible with a single transistor which eliminates the need for combiners and associated losses.
This pallet is optimized for 28-32 volt operation. Using a lower voltage will result in lower efficiency and output power.
We sell a high quality 1000 watt low pass filter for FM broadcast applications.
Technical specifications:
- Shipping Weight: 1.1Kg
- 86-110MHz 48 Volts
- Input/Output 50 ohms
- Pout 500W Minimum with a 4-4.5W input
- 21dB gain minimum.
- Low distortion Class AB push-pull.
- Small size: only 2.75 x 5.0 in
- 70% efficiency typical.
- Power requirements 21.5 to 23 Amps @ 32 volts, 500W output.
- Bias disable pads facilitate integration into amplifier systems that employ automatic VSWR protection.
- The PCB and transistors are mounted to a 1/4 inch CNC machined nickel plated copper baseplate.
- For maximum service life we suggest that output power be limited to 450 watts!!
