Model SM2025-38LS
2000-2500 MHz
6 Watt Ultra-Linear Power Amplifier
FOR BROADCAST APPLICATIONS
The
SM2025-38LS
is a 2.0 to 2.5 GHz
solid state GaAs FET amplifier designed for
demanding applications such as digital
video transmission. The amplifier provides
51 dB of linear gain with a typical P1dB of
+39 dBm. Our proprietary pre-distortion
technique provides enough linearity for
approx. 2 Watts of COFDM output at
>40dBc ACP. It is available in modular
form (standard), as a lab unit or in 19” rack
mountable form.
