Our Requirement as below.

L Band Amplifier we have the below requirements.

Frequecy Range- 1 Ghz to 1.5GHz

RF Output – 25w

Modulation – COFDM

Operating Voltage – 28VDC

RF Input – 10 dBm

Type Class A Linear Amplifier.

Signal type Needed —COFDM

.Freq. Range –1000Mhz to 1500 Mhz

Input signal level—-0dbm to 10dbm

output power—25 watt@ COFDM Modulation

Input DC supply—-28v DC size of the amplifier should be as compact as possible.INPUT/OUTPUT RF connectors SMA Female

A: 1000Mhz to 1500Mhz is too wide for us. Our power amplifier frequency range max supports 60 MHz. Other demands are no problem.
