The Varian CPI VZM6993G61575 is a specialized RF power amplifier component manufactured by Communications & Power Industries, part of Varian’s established TWT amplifier product portfolio. This device delivers high-gain, high-power RF amplification across defined frequency bands, engineered for demanding test and measurement environments where reliability and performance consistency are critical.
Technical Specifications
The VZM6993G61575 incorporates a metal-ceramic traveling wave tube (TWT) architecture with integrated high-efficiency switching power supply design. Output impedance is standardized at 50 ohms nominal, with N-type connectors for RF input and output. Harmonic content performance varies across the operating band, typical values ranging from −3 dBc at lower band edges to −15 dBc at upper band edges without optional harmonic filtering. Input and output VSWR are specified at 2.0:1 typical.
