Uses grounded-gate CP643 preamp having high dynamic range,2N5109 oscillator injection amplifier, and 3N200 IF amplifier in combination with Minilabs SRA3H double-balanced mixer. Third-order intercept point is +30 dBm. Oscillator requirementis -1 to +2 dBm (200 to 280 mV across 50 ohms) AGC range is greater than 50 dB Levels shown in parentheses are for 0 dBm (224 mV) at input and zero AGC voltage.-U. L.
