Current state of the art in IDG:
- Good transitions to waveguide and Co-ax
- Well matched array antennas
- Wideband flared slot antennas
- Broadband, flat response directional couplers
- Diode mounts for detector, mixer and control applications
- Very wideband twin-layer configuration
- Wideband non-reciprocal effects
- Microstrip and Co-planar loaded IDG
- Broadside coupled strip directional couplers
It is now feasible to fabricate entire receiver, and antenna
feed network in IDG with good performance.
