Product Description
800MHz to 1000MHz High Power LDMOS Broadband Amplifier 53 dB Gain 200 Watt Past
VPAM-800-1000-200 is a high power amplifier that operates between 800 MHz and 1000 MHz and generates 200 watts of saturated output power. The module utilizes LDMOS and chip-and-wire technology in the manufacturing process that ensures stateof-the-art power performance with excellent power-to-volume ratio that’s ideal for broadband high power linear applications. This Class AB amplifier is designed for a 50 ohm input/output impedance and offers high efficiency and high linearity, operating over a wide dynamic range with impressive typical performance that includes 53 dB gain, ±1 dB gain flatness, -15 dBc harmonic suppression, -60 dBc Spurious, and a maximum input power level of +35 dBm. Typical DC bias requirements include +28V and 25A of current. The module uses an SMA female input and output connector. The DC interface incorporates a D-Sub 7 pin male connector for DC bias, Shutdown with TTL logic control, Current Sense, and Temperature Sense functions. A mating female D-SUB socket connector is included. The rugged amplifier design operates over wide temperature range from -40°C and +60°C and can withstand relative humidity exposure up to 95% maximum.
