Product Overview: HMC963LC4 - Analog Devices Inc.

The HMC963LC4 is a high-performance, wideband, GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC Voltage Controlled Oscillator (VCO) designed by Analog Devices Inc. to address a variety of applications requiring precise frequency generation and modulation. Its design is optimized to deliver exceptional phase noise performance and high output power across a wide frequency range, making it an ideal component for use in microwave radios, test instrumentation, and military radar systems.

This VCO operates over a frequency range of 7 GHz to 13 GHz, which can be tuned via an analog voltage control input. It offers a typical tuning sensitivity of 1200 MHz/V and a phase noise performance of -100 dBc/Hz at 100 kHz offset, ensuring clean signal generation for high fidelity applications. The HMC963LC4 is packaged in a compact 4x4 mm ceramic leadless chip carrier (LCC), which is suitable for surface mount technology (SMT) and offers excellent thermal performance.

The device integrates resonators, negative resistance devices, and varactor diodes, which together provide a complete VCO solution that simplifies design and reduces component count. It also features an output buffer amplifier that provides isolation between the VCO and the load, which helps to maintain stable operation over various load conditions.

Analog Devices Inc. has engineered the HMC963LC4 to deliver robust performance with a supply voltage of +5V and a typical current consumption of 95 mA. This VCO has been built with reliability in mind, meeting stringent quality standards and ensuring consistent performance in demanding environments.

For designers looking for a versatile and high-quality VCO, the HMC963LC4 from Analog Devices Inc. offers an excellent blend of wideband capability, low phase noise, and ease of integration, making it a top choice for sophisticated frequency generation needs.
