Specifications include, but are not limited to: 1 Microwave Power Amplifier 1: 1-1 Frequency band must cover at least the 0.7 to 6.0 GHz, instantaneously. 1-2 Minimum saturated output power of 250 W Continuous Wave (CW) with an input power level of 0 dBm. Higher output power levels are acceptable. 1-3 Power output at 1 dB compression point (P1dB): greater than 200W CW. 1-4 Input and output impedance of 50 Ohms with a VSWR of 2:1. 1-5 Third-order output intercept point higher than 60 dBm. 1-6 Second and third-order harmonic distortions at full saturated power (250 W) lower than -18 dBc. 1-7 Mismatch tolerance: The amplifier must operate without damage of oscillation for any output impedance. It is possible that during experiments, the output impedance presented to the amplifier may change significantly (e.g., change from 50 Ohms to almost short or open depending on the nature of the experiment). The amplifier must have protection mechanisms in place to ensure that such changes will not permanently damage the system. 1-8 Forced-air self-contained cooling. 1-9 Input and output connectors: N-type female. 1-10 The amplifier must include remote control functionality with at least one of the following interfaces: GPIB, Ethernet, or USB. 1-11 The RF input and RF output connectors must be on the front panel. 1-12 A front panel display showing the real-time forward and reflected power levels. 2 Microwave Power Amplifier 2: 2-1 Frequency band must cover at least the 6.0 to 18 GHz, instantaneously. 2-2 Minimum saturated output power level of 250 W Continuous Wave (CW) with an input power level of 0 dBm. Higher output power levels are acceptable. 2-3 Harmonic distortion: Not to exceed -8 dBc. 2-4 Noise power density lower than -65 dBm/Hz. 2-5 Input connector: Type N Female. 2-6 Input impedance: 50 Ohms with VSWR not to exceed 2.5:1 across the band. 2-7 Output connector: Either rugged coaxial type connectors (e.g., N-type) or double-ridged waveguide connectors (e.g., WRD-650). 2-8 Output impedance: 50 Ohms with VSWR better than 2.5:1. 2-9 Mismatch tolerance: The amplifier must operate without damage of oscillation for any output impedance. It is possible that during experiments, the output impedance presented to the amplifier may change significantly (e.g., change from 50 Ohms to almost short or open depending on the nature of the experiment). The amplifier must have protection mechanisms in place to ensure that such changes will not permanently damage the system. 2-10 Forced-air self-contained cooling. 2-11 The amplifier must include remote control functionality with at least one of the following interfaces: GPIB, Ethernet, or USB. 2-12 The RF input and RF output connectors must be on the front panel. 2-13 A front panel display showing the real-time forward and reflected power levels.
