High performance HBV multipliers monolithically integrated onto a host quartz substrate
Tóm tắt
Fully integrated monolithic circuits incorporating InP-based heterostructure barrier varactor (HBV) frequency multipliers have been fabricated via epitaxial lift-off and transfer-substrate techniques onto a quartz substrate. We have obtained a maximum output power of 6 mW at 288 GHz corresponding to an overall efficiency of 6%. In addition we have observed a 45 GHz 3 dB bandwidth centered around 300 GHz for a constant input power of 70 mW. We also report on the design of a multiplier block in a fin line technology making use of smoothly corrugated tapered sections for mode matching and filtering.
