1300W FM Pallet amplifier
[MRF1K50h]
 


The new NXP LDMOS MRF1K50h makes it possible to create highly rugged 1300W pallets for high VSWR industrial and broadcast (analog and digital) applications.

Pout 1350W with 12.5W input typ.

Voltage supply: 50V DC
Supply current: 32A
Operating Temperature range: 0 to +70 C ( at Device Flange )
Storage Temperature range: -30 to +90 C
Load Mismatch: 65:1 (all phase angle)

Frequency Range: 87.5 to 108 Mhz
Power Gain: 22dB typ. 1dB
Power Output: 1250W typ. 1350W max.
Power Input: 10W typ.
Efficiency: 85% max. @ 108Mhz FM CW.
Supply Voltage: 50V typ, 52V max
F2 Second Harmonic: -35dB typ.
F3 Third Harmonic: -35dB typ.


IMPORTANT:
- 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.

Quantity discount is available and shipping becomes a lot cheaper per unit as quantity goes up. For additional info and prices please ask for a quote here.
