One or more of the following United States patents apply: 4,760,352; 5,787,117; and 7,260,375. Unless noted otherwise, all specifications are listed at TA = +25 ±2 °C, VCC = nominal voltage ±0.01 VDC, and load impedance = 50 with VSWR 1.5:1. The design, manufacturing process, and specifications of this device are subject to change without notice. Applies to oscillator only and not to sidebands caused by external electrical or mechanical sources. (Dedicated external voltage regulation with low-frequency filtering for the DC power supply and proper circuit board layout are recommended for optimum spectral purity.) For specified maximum operating load VSWR,any angle, at FO. No instability or damage will occur for any passive load impedance. For any combination of VCC and TA within the specified operating ranges. Applies for any combination of Note 5 and 6 conditions. Start-up time is defined as the time from when 90% of Vcc is applied to the Enable Pin until the RF output reaches 90% of its steady-state output level. www.RFM.com E-mail: [email protected] © 2011 by RF Monolithics, Inc.
