This paper covers two recent progresses on MW and MMW MMIC technologies.One is the high efficiency and high power density pHEMT technology for power amplifier MMICs. The nonlinear drain resistance is found to be the cause of large power loss at millimeter-wave, although it acts like the conventional resistor at low frequency. A new device structure is proposed to overcome this problem, and results in excellent performance of 0.65W/mm output power and 35% PAE at Ka band. The other topic is the InGaP HBT oscillator enhancing the output power without any reduction of the phase noise. At 40GHz, 6dBm output power and -113dBc/Hz phase noise has been demonstrated. The 2nd harmonic matching is the key to achieve high output power and low phase noise simultaneously. Results are supported by both simulations and measurements.

“…A frequency multiplier (Mini-Circuits MK-5) can directly generate the harmonics (multiple) of the input signal in the several GHz range. [27][28][29][30] Experimentally, we realize the microwave signals of 1.4 and 2.8 GHz commonly used in the NV center by frequency multiplication. A subsequent band-pass filter selects the desired harmonic frequency and removes the unwanted fundamental and other harmonics from the output.…”

“…The frequency multiplication technique is often used in frequency syn- thesizers and communication circuits. [27][28][29][30] The IF signal from an arbitrary waveform generator (AWG) can be directly multiplied and converted to the microwave field. Different from the IQ modulation technique, our approach only needs one channel of the IF signal and does not require two-way signals and orthogonal local oscillators.…”

Coherent manipulation of nitrogen-vacancy centers in diamond via frequency multiplication

Nitrogen-vacancy (NV) centers in diamond as ideally individual spin quantum systems can be coherently manipulated by microwave fields. Compared to the traditional method using the IQ (In-phase/Quadrature) mixer with a local oscillator and intermediate-frequency (IF) signals, we report an effective and technically simple method to generate the required microwave field by frequency multiplication and realize coherent manipulation of the NV center’s electron spin. After frequency multiplication, the IF signal can be directly converted to the high-frequency microwave field with adjustable pulse width, frequency, phase, and amplitude. A series of spin dynamics applications such as Rabi oscillation, free induction decay, and spin-locking are executed, which verified its performance and feasibility. Frequency multiplication can overcome the problem of clock synchronization between the local oscillator and IF signal and greatly reduce the complexity of the experimental system. The method can be easily used to realize a more complex quantum control sequence such as dynamic decoupling and extended to a wide range of spin-based quantum information applications in the future.

Microwaved RF frequency multipliers are electronic devices that generate signals having frequencies that are integral multipliers of their input signal frequencies. These devices have applications in electronic instruments, radar, electronic warfare, and communication systems. This article covers theory and design of these devices that operate from the megahertz to millimeter‐wave regions. Detailed discussions of both passive and active realizations are included along with state‐of‐the‐art practical design examples. Over 170 references covering the current multiplier technology in RF and microwave bands are included.
