300W FM pallet P-FM300AFM  


300W FM pallet amplifier with Freescale LDMOS
Designed primarily for FM application, with a reliable Power Ldmos device. This amplifier is suitable for any CW or pulsed application. This module is for system integrators who will attach the pallet to their own cooling system (heatsink and fan) and incorporate their own low pass filter.
 
Technical specifications:
- Pout (min): 250 Watts 
- Pout (nom): 300 Watts 
- Pout(max): 350 Watts 
- Frequency: 87,5-108MHz 
- Power Gain: 20dB typ. 
- Power Input: 33-34.7dBm
- Efficiency 75-80% typ. 
- Power Volts 48V nominal
- Device used: MRF6V2300NR1
- Dimensions: (LxWxH) 60x65x30mm
- Second harmonic -35dB min.
- Operation: Class C
- In/out impedance: 50 ohm
- Power gain variation: +-1.5dB
- Second harmonic: -30dBc
- Third harmonic: -45dBc
- Load Mismatch (full power, all phase angle): 2:1

Quick Facts:
- No RF assembly or circuit tuning
- 250 watts min output power
- 20dB typical gain at 108MHz
- High efficiency MOSFET design 


IMPORTANT:
- This amplifier can work without power reduction at 2:1 VSWR load matching. Please remember that this specification is valid only in CW or FM application, pulsed signal or other kind of modulation can affect this limit.

- Due to the High gain of this pallet, a good shielding between final stage and any driver/low power stage is required. Please foresee a good RF choke also on the supply wiring.

- Excessive drive level can damage this amplifier, design of equipment where the amplifier will be mounted, must foresee an appropriate protection circuits. Max input level is + 6dB referred to
the typical input power.

- Amplifier efficiency is function of supply voltage, in order to obtain max efficiency please reduce supply in function of desired output power. Generally best compromise between efficiency and harmonic emission, is obtained when the amplifier work at about 2-3 dB of gain compression.

- RF pallets are sensitive devices, if you do not have sufficient experience please consider a finished product instead. They can be burned by applying too much drive power, too high supply voltage, not using proper heatsink, using filter with unsufficient specifications, connecting mismatched loads or no load at all and also by soldering coax with too long leads. For this reason there is no warranty for any pallet. We do assure you that every pallet is tested and is 100% operational as it leaves our workshop.
