IN STOCK!
Ultra - Linear (Class AB) RF Power Amplifier Module built & tested (power brickwihtout heatsink)
It is supplied with its own base plate but it needs a large heatsink under the baseplate for continuous operation as it runs HOT!
Frequency Range: 2400 - 2500 MHZ
RF Gain: 33 dB
RF output: 250 W CW
DC Power: +28 V DC (15A)
With interstage isolator
* The amplifier can generate 250W at P1dB across the frequency band of 2.400 -2.500 MHz when kept at a baseplate temperature of 20 C.
For proper operation and protection of the output stage passives below their max operating temperature, we recommend to back off the output power at ~150W when the baseplate reaches 90C.
All the above numbers are applying to continuous CW operation, and proper termination to 50 Ohm load.
ATTENTION: This amplifier needs a perfect load, the transistor fails at VSWR 2:1
Double-check your antenna before connecting this amplifier. A good idea is to use an isolator, we are currently looking for suitable ones to offer. High VSWR may also damage the PCB, which cannot be corrected!
This amplifier is suitable for digital TV transmission if it operates at 100 W (200 W peak), since the signal's crest factor is 3 dB. Ensure lower drive power in order to achieve these levels. Always measure the input power in order to prevent overload. Since its gain is 33 dB, for a CW signal of 200 W output power (53 dBm = 200 W) it needs 53-33 = +20 dBm (100 mW) input power. For the DTV signal having a crest factor of 3 dB, it needs 3 dB less, i.e., +17 dBm. Better stay on safe levels, don't push it hard!
This amplifier is very linear, it is suitable for QAM or most other applications. It is well tested and already in use for a variety of applications.
In a case of transistor damage, we can replace at an agreed price, on the condition the PCB is not damaged. If the PCB has damages, we cannot provide any help!
The amplifier is shipped as pictured in the photos, without box, heatsink or other peripherals, for keeping costs down. A complete amplifier like this would have a much different cost.
We can help for the heatsink, please drop us an email to ask for availability.
MIL-SPEC Version is also available, please contact us for details.
SV1AFN.com amplifiers are available for laboratory, experimentation, radio amateur, export, military, OEM & licensed customers only. It is the responsibility of the purchaser/installer/operator to insure that only approved equipment/systems are deployed.
