Description
The US Air Force is seeking information from qualified vendors for the supply of C & X-Band 300W Amplifiers. The amplifiers should have specific electrical and mechanical characteristics, including a frequency range of 5.5GHz – 10.5GHz, input/output impedance of 50 ohms, and output power of greater than 55dBm. The amplifiers should also have a duty cycle of 15% max, PAE of 18% typical, and gain at Psat of greater than 55dB typical. The package type should be a connectorized module with dimensions of 12L x 10W x 5D inch max. The operating temperature range should be -20C to +65C min, and the storage temperature should be -40C to +85C min.
Some key points to consider are:
• The amplifiers should have a GaN pulsed amplification type
• The input power should be 0dBm typical, with a maximum of 33dBm
• The gain flatness should be less than +/-3dB at 0dBm input
• The VSWR should be less than 3:1
• The biases should be VD less than or equal to 40v DC
• The max DC power should be less than 1500W
• The input/output return loss should be less than 15dB
• The blanking type should be RF gating, with a blanking logic of TTL 3v to 5v
• The blanking response time should be less than 2uS RF on/off
