ARB-704 Buffer for amplifier keying

Keys nearly any PA Useable with nearly any transceiver Noiseless operation, transistor keying Fast, QSK capable Simple wiring Every transceiver has a keying output for an amplifier – but not all those outputs are capable of keying the high voltages or currents of an amplifier. High voltages or voltage peaks can destroy the keying stage…

40 °C Precision Crystal Heater

The precision crystal heater provides temperature stabilization for crystals. The circuit, which is built on AL2O3 ceramic substrate, has to be mounted on the 40 °C thermostat crystal. Then, the crystal is heated to 40.8 °C with a regulation accuracy of-better than 0.1 °C. This provides high frequency stability. The precision crystal heater is a…
