Model SM2025-42LS 2000 - 2500 MHz 15 Watt Ultra-Linear Power Amplifier FOR BROADCAST APPLICATIONS The SM2025-42LS 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 52 dB of linear gain with a P1dB of +42 dBm. Our proprietary pre-distortion technique provides enough linearity for approx. 3 Watts of COFDM output at >40dBc ACP. It is available in modular form (standard), as a lab unit or in 19” rack mountable form. Features • • • Integrated Linearizer Single Power Supply Thermal Protection with Auto Reset Options • • • Forward Power Detection Logic On/Off Control Integral Heatsink Configurations • • • Module (Standard) Laboratory Unit 19” Rack Mount Parameter Specification Frequency Range 2.0 – 2.5 GHz Pout (P1dB) +42 dBm (typ.)
