A 474 GHz HBV Frequency Quintupler Integrated on a 20μm Thick Silicon Substrate

چکیده
We present a silicon integrated Heterostructure Barrier Varactor (HBV) frequency quintupler ( 5) operating between 440 GHz and 490 GHz. By epitaxial transfer of InP-based HBV material structure onto silicon-on-insulator (SOI), a uniform and accurate thickness (20 m) of the frequency quintupler chip is achieved. In a single stage this device delivers 2.8 mW of output power at 474 GHz, when pumped with 400 mW at 94.75 GHz, corresponding to conversion efficiency of 0.75%. The present device exhibits a 3-dB bandwidth of 4%.

A 200-GHz integrated resistive subharmonic mixer based on a single chemical vapor deposition graphene field-effect transistor (G-FET) is demonstrated experimentally. This device has a gate length of 0.5 μm and a gate width of 2× 40 μm. The G-FET channel is patterned into an array of bow-tie-shaped nanoconstrictions, resulting in the device impedance levels of ∼50 and the ON–OFF ratios of ≥4. Th...
متن کاملFabrication of thick silicon nitride blocks embedded in low-resistivity silicon substrates for radio frequency applications
Thick silicon nitride blocks embedded in silicon wafers were recently proposed as a substrate for RF devices. In this paper we show that deep trenches filled with silicon nitride—having thin slices of monocrystalline silicon in between—already result in a significantly improved RF behavior. Measurement results are presented on RF coplanar waveguides using solid silicon nitride blocks and silico...

متن کاملSelf-aligned wafer-level integration technology with an embedded faraday cage for substrate crosstalk suppression
A modification to a recently developed chip/wafer integration technology has proven to be very effective in suppressing the substrate crosstalk for mixed signal systems. In this implementation, analog and digital chips are fabricated on separate dies, and then integrated on a single Si substrate using a Self-Aligned Wafer-Level Integration Technology. A truly grounded faraday-cage structure is ...
