Microchip Launches Ultra-Low Phase Noise Voltage-Controlled SAW Oscillators for Aerospace and Defense
New VCSO Family Delivers Precision Frequency Control for Mission-Critical Applications

Microchip Technology has introduced the new 101765 family of Voltage-Controlled SAW Oscillators (VCSOs), designed to provide ultra-low phase noise and operate at 320 MHz and 400 MHz. These VCSOs are engineered for mission-critical applications like radar and test and measurement systems, offering precise frequency control and enhanced signal clarity to improve overall system performance.
The 101765-320-A VCSO delivers ultra-low phase noise of 166 dBc at 10 kHz offset with a noise floor of 182 dBc, making it ideal for applications like Active Electronically Scanned Array (AESA) radar and instrumentation systems that require high fidelity in phase-locked loop timing.
Key Features and Benefits
- Ultra-Low Phase Noise: Enhances lower limit detection for radar and sensing applications.
- Compact Form Factor: Available in a 1 inch × 1 inch hermetic Kovar package, optimized for Size, Weight, Power, and Cost (SWaP-C).
- Power-Efficient Design: Operates with supply voltages from 4.75 to 15.75V and a current of 111 mA.
- MIL-PRF-38534 Screening: Ensures high reliability for aerospace and defense applications requiring military-grade components.
“Microchip continues to deliver high-performance timing products with ultra-low phase noise at competitive prices, catering to the precise needs of our customers in aerospace and defense,” said Leon Gross, corporate vice president of Microchip’s discrete products group.
The 101765 VCSO family supports applications that demand reliability in harsh environments, with available options to meet ITAR, EAR, and classified specifications. These devices are suitable for center frequencies ranging from 30 MHz to 2.7 GHz, providing a versatile solution for ruggedized applications.
