ADI Unveils Three Ultra-Wideband Quad-Band VCOs
Suitable for high-performance measuring equipment and defense applications
No lower harmonic tones due to built-in oscillator


Analog Devices (ADI) announced on the 4th that it is launching a family of quad-band voltage-controlled oscillators (VCOs) that provide wideband functionality without compromising phase noise performance.

The new △HMC8074 △HMC8362 △HMC8364 quad-band VCOs offer ultra-wideband capabilities with a fundamental frequency range of 8.3 GHz to 26.6 GHz, enabling a wider RF response and greater frequency flexibility than narrowband VCOs. They also offer fast transition times between VCO bands without voltage overshoot.

It offers lower phase noise than conventional single-band, wideband VCOs, and reduces loop filter design complexity with lower tuning voltages and a narrower sensitivity-to-frequency characteristic. Current consumption is kept low, typically around 60 mA, and the built-in oscillator eliminates the generation of lower-order harmonic tones due to the device's multiplication effect.

Three new quad-band VCOs, suitable for high-performance measurement equipment and aerospace and defense applications, are available in a compact 40-pin 6 × 6 mm LFCSP SMT package.
