Description
The BHED22748-200 is a 400 MHz, 200 W RF amplifier from Comtech PST. Amplify RF and Microwave signals to measure, test, and design circuits. Applications include radio communications, cellphones, EMI testing, and much more. Additional Features: Frequency range: 225-400 MHz Output Power: 200 Watts KVA: 2.6 Digital Interface: IEEE488 Class of Operation: AB Linear RF Input Power: 1mW (0dBm) for full output power RF Input Signals: CW, AM, FM, Phase and Pulse Modulation Harmonics: B.W. Spurious: -60dBc Max Input VSWR: 2.0:1 nominal Output Load VSWR: 1.3:1, full forward power output 2:1, 0.5dB turndown nominal infinite, 10dB turndown nominal AM Distortion (85% D.O.M.): 10% Max Pulse Rise/Fall Time (typical): 150ns Noise Power Output: -86dBm/Hz typical (model dependent) Maximum RF Input: +8dBm RF Connectors Input: Female Type N, Rear Panel; Output: Female Type N or SC, Rear Panel (model dependent) AC Input: Power Factor Corrected Universal Input 100-240Vac, 50/60Hz Efficiency (AC to RF): 16% typical AM, FM, CW, pulse & phase modulated signal inputs Field-replaceable modules Graceful degradation High efficiency switching power supplies Standard 19” Rack Mount Configuration Applications EW/ECM systems Communication systems AM/FM transmitter boosters TWT replacement RFI/EMI testing High power calibration testing Load VSWR Protection Series BHE amplifiers provide load VSWR protection via an electronic power output turndown system employing negative feedback techniques. The system is self-correcting as a function of load VSWR to infinity, at any phase angle. The typical response time is 60 μsec. Input/Output Overdrive Protection A leveling loop system protects the amplifiers from input overdrive signals of up to +8 dB. Under an overdrive condition, the output power is controlled at a level 2 to 10% above the rated output power at normal input level conditions. A power overshoot will be present at the beginning of the overdrive condition, which is a function of the amount of overdrive. Note that this characteristic can be used to obtain a 1 to 3 dB output (or more depending on model) power increase for narrow pulses with a low duty cycle. The image is a representation of the actual product. Please see specifications and data sheet for details.

Load VSWR Protection

Series BHE amplifiers provide load VSWR protection via an electronic power output turndown system employing negative feedback techniques. The system is self-correcting as a function of load VSWR to infinity, at any phase angle. The typical response time is 60 μsec.

Input/Output Overdrive Protection

A leveling loop system protects the amplifiers from input overdrive signals of up to +8 dB. Under an overdrive condition, the output power is controlled at a level 2 to 10% above the rated output power at normal input level conditions. A power overshoot will be present at the beginning of the overdrive condition, which is a function of the amount of overdrive. Note that this characteristic can be used to obtain a 1 to 3 dB output (or more depending on model) power increase for narrow pulses with a low duty cycle.
