AADPCB AOM Driver
The MOGLabs AADPCB is a low-cost yet versatile VCO-based RF driver for AOMs, with frequency stability and modulation capabilities comparable with much more expensive alternatives. Running from a single +24 volt supply it includes two selectable VCOs that enable operation from 70 to 200 MHz and provides RF output up to 4 watts (+36 dBm). Two external analogue inputs provide FM and AM with 1 MHz bandwidth for laser noiseeating and frequency locking applications. A third input provides fast on/off TTL control. The AAD is an all-in-one replacement for a tuneable oscillator (VCO), variable attenuator (VCA), RF switch, and output coupler, all running from a single +24V supply.
Features
- High output power: up to +36 dBm per channel

- RF power out and monitoring out ( –22 dBc)
- External digital input for fast on/off
- 10-turn frequency, single-turn power controls
- High stability VCO, low phase noise
