| 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. Parameter Specification 2.0 - 2.5 GHz +42 dBm (typ.) +35 dBm 1 +61 dBm 52 dB .5 dB .5 dB 1.8:1 / 1.5:1 +12 Volts 5.5 Amperes (operational) 6.0 x 2.5 x .56 inches SMA Female -10 to +60C 2 95% Non-condensing Up to 10,000 feet above Sea Level Features * * * Integrated Linearizer Single Power Supply Thermal Protection with Auto Reset Frequency Range Pout (P1dB) Pout (Linear) Output Third Order Intercept Point (OIP3) Linear Gain Gain Flatness (over full band) Gain Change (over temperature) VSWR (Input/Output) DC Input Voltage DC Input Current Mechanical Dimensions Options * * * Forward Power Detection Logic On/Off Control Integral Heatsink Configurations * * * Module (Standard) Laboratory Unit 19" Rack Mount 1 Input signal is 7.68 MHz wide with a 9.49 dB peak to average. The test measurement is in a 10 MHz bandwidth, offset by 10 MHz, with an ACP of 40 dBc. -30 o C is TBD RF Connectors Operating Temperature Operating Humidity Operating Altitude 2 1007 Whitehead Road Ext., Trenton, NJ 08638 Tel: (609) 538-8586 Fax: (609) 538-8587 Email: sales@stealthmicrowave.com Web site: www.stealthmicrowave.com Model SM2025-42LS 2000 - 2500 MHz 15 Watt Ultra-Linear Power Amplifier FOR BROADCAST APPLICATIONS DIMENSIONS IN INCHES +VDC GND ON/OFF RF OUT INCORPORATED RF IN FWD DET Pin RF INPUT RF OUTPUT GND FWD Description Input Connector ( SMA Female ) Output Connector (SMA Female) Ground Turret Forward Power Detector +12VDC ON/OFF DC Input Voltage TTL Logic On/Off Values -8 dBm (max.) + 42 dBm @ P1dB (typ.) --+ 35dBm COFDM Output Power + 2.0 Volts.
