A small 4 way distribution amplifier that fits inside the BG7TBL 2016-05-31 GPSDO with configurable square or sine wave outputs.
Can be configured with square wave or sine wave output based on populating or bridging the final stage passives, input is a square wave tapped off from GPSDO internal circuitry (works with both square and sine variants) and sized to fit above the heatsink found in the BG7TBL GPSDO 2016-05-31 variant (others as well, but not much older board configurations).
Output is approx. 2Vpp square wave or 1Vpp sine wave configurable per channel built as specified. Parts are around $12 US, with the vast majority of the cost in the 4 BNC connectors.
