Tiny SMD OCSOs target radar applications

November 27, 2017 // By Julien Happich
Rakon has released new Oven Controlled SAW Oscillators (OCSOs) in a miniature 25.4- x 22- x 12.7-mm SMD package, currently available in 400 MHz, 500 MHz, 600 MHz, 800 MHz, 1 GHz and 1.2 GHz and all designed to be soldered by reflow.

Among them, the LNO800E1 is a low noise, low power Oven Controlled, Voltage Controlled, SAW Oscillator (OCVCSO) operating at 800 MHz and powered by a low +5V supply. The 800 MHz signal is generated from a 400 MHz fundamental frequency, followed by a low noise frequency doubler.

This product series is designed for ground-based and shipboard RADAR, test equipment, and airborne systems where size and weight are critical. The device has exhibits an excellent phase noise performance (-137 dBc/Hz at 1 kHz offset, -160 dBc/Hz at 10 kHz offset, 167 dBc/Hz noise floor typical values), with a broadband jitter less than 10fs (frequency offset: 10 kHz to 100 MHz).
