| (R) RF1355 390.0 MHz SAW Filter * * * * * Ideal for 390.0 MHz Transmitters Very Low Series Resistance Quartz Stability Rugged, Hermetic, Low-Profile TO39 Case Complies with Directive 2002/95/EC (RoHS) Pb The RF1355 is a true one-port. surface-acoustic-wave (SAW) filter in a low-profile TO39 case. It provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmiters operating at 390.0 MHz.

Observe precautions for handling. Notes: 1. 2. 3. 4. 5. 6. 7. 8. 9. Frequency aging is the change in fC with time and is specified at +65C or less. Aging may exceed the specification for prolonged temperatures above +65C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years. The center frequency, fC, is measured at the minimum insertion loss point, ILMIN, with the resonator in the 50 test system (VSWR 1.2:1). The shunt inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically, fOSCILLATOR or fTRANSMITTER is less than the resonator fC. One or more of the following United States patents apply: 4,454,488 and 4,616,197 and others pending. Typically, equipment designs utilizing this device require emissions testing and government approval, which is the responsibility of the equipment manufacturer. Unless noted otherwise, case temperature TC = +25C2C. The design, manufacturing process, and specifications of this device are subject to change without notice. Derived mathematically from one or more of the following directly measured parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO. Turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO. The nominal frequency at any case temperature, TC, may be calculated from: f = fO [1 - FTC (TO -TC)2]. Typically, oscillator TO is 20C less than the specified resonator TO. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance CO is the static (nonmotional) capacitance between pin1 and pin 2 measured at low frequency (10 MHz) with a capacitance meter. The measurement includes case parasitic capacitance with a floating case. For usual grounded case applications (with ground connected to either pin 1 or pin 2 and to the case), add approximately 0.25 pF to CO. RF Monolithics, Inc.
