Mission-critical applications like radar and test and measurement require specialized components with precise frequency control and ultra-low phase noise to enhance signal clarity, stability and overall system performance. To provide the aerospace and defense market with specialized technology for generating precise signals and frequencies, Microchip Technology announced its new 101765 family of voltage-controlled SAW oscillators (VCSOs) designed to deliver ultra-low phase noise and operate at 320 and 400 MHz.

The 101765-320-A VCSO delivers ultra-low phase noise performance of 166 dBc at 10 kHz offset and a 182 dBc floor. Low phase noise is crucial for improving the lower limit of detection in radar and other sensing applications. These devices are optimal for radar and instrumentation systems such as active electronically scanned array that demand high fidelity in critical phase-locked loop timing applications.

Available in a small form factor, 1 × 1 in. hermetic Kovar package, the VCSOs are designed for applications where size, weight, power and cost (SWaP-C) are important factors. The VCSOs are offered with supply voltages from 4.75 to 15.75 V and a supply current of 111 mA to provide a power-efficient timing solution.

“Microchip continues to deliver ultra-low phase noise and high-performance timing products at a competitive price point to meet the needs of our customers,” said Leon Gross, corporate vice president of Microchip’s discrete products group. “Customers can choose Microchip for their timing needs and select other components for their application including FPGAs, MPUs, MCUs, RF, power management, security and connectivity.”

For aerospace and defense customers who require a higher degree of reliability, the 101765 VCSOs are available with MIL-PRF-38534 screening. The screening process is designed to ensure only the highest reliability components are used in critical applications where failure is not an option, such as in military and aerospace systems.

The 101765 VCSO family is a fresh addition to Microchip’s family of SAW products for aerospace and defense applications, which are designed to offer levels of high reliability for robust and mission-critical environments. They are available in a wide range of package options for ruggedized applications and support a center frequency range from 30 MHz to 2.7 GHz. Additionally, Microchip can address ITAR, EAR and classified specifications for hardware to meet the customer’s security requirements.
