HR395.5 395.5MHz One-Port SAW Resonator For Wireless Remote Control Approved by: Checked by: Issued by: SPECIFICATION PRODUCT: MODEL: SAW RESONATOR HR395.5 QCC8C HOPE MICROELECTRONICS CO.,LIMITED Tel:+86-755-82973806 Fax:+86-755-82973550 E-mail: sales@hoperf.com Page 1 of 1 http://www.hoperf.com SAW Resonator HR395.5 The HR395.5 is a true one- port surface- acoustic- wave( SAW) resonator in a low- profile QCC8C case. It provides reliable fundamental- mode quartz frequency stabilization of fixed- frequency transmitters operating at 395.5 MHz. 1.Package Dimension (QCC8C) Pin 2 6 4,8 1,3,5,7 Sign Data (unit: mm) Sign Configuration Terminal1 Terminal2 Case Ground Empty Data (unit: mm) A B C D 2.08 0.6 1.27 2.54 E F G H 1.2 1.35 5.0 5.0 2.Marking 3.Equivalent LC Model and Test Circuit HR395.5 Color: Black or Blue 4.Typical Application Circuit 1) Typical Low-Power Transmitter Application 2) Typical Local Oscillator Application 5.Typical Frequency Response 6.Temperature Characteristics Tel:+86-755-82973806 Fax:+86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com SAW 7.Performance 7-1.Maximum Ratings Rating CW RF Power Dissipation DC Voltage Between Any Two Pins Case Temperature Resonator HR395.5 Value +10 30V -40to+85 Units dBm VDC 7-2.Electronic Characteristics Characteristic Center Frequency (+25 ) Insertion Loss Quality Factor Temperature Stability Unloaded Q 50 Loaded Q Turnover Temperature Turnover Frequency Frequency Temperature Coefficient Frequency Aging Absolute Value during the First Year DC Insulation Resistance Between Any Two Terminals Motional Resistance RF Equivalent RLC Model Motional Inductance Motional Capacitance Shunt Static Capacitance Absolute Frequency Tolerancefrom433.920MHz Sym fC fC Minimum 395.425 Typical 75 1.3 12980 1,800 Maximum 395.575 1.8 Units MHz kHz db IL QU QL T0 f0 FTC |fA| 1.0 RM LM CM C0 25 40 fC 0.037 10 16.1 84.139 1.9266 2.3 55 KHZ ppm/ 2 ppm/yr M 23 H fF pF CAUTION: Electrostatic Sensitive Device. Observe precautions for handling ! 1. Frequency aging is the change in fC with time and is specified at +65 or less. Aging may exceed the specification for prolonged temperatures above +65 . Typically, aging is greatest the first year after manufacture, decreasing in subsequent years. 2. The center frequency, fc ,is the frequency of minimum IL with the resonator in the specified test fixture in a 50 test system with VSWR 1.2 : 1. Typically, foscillator or ftransmitter is less than the resonator fc. 3. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufacturer. 4. Unless noted otherwise , case temperature Tc=+25 2. 5. The design, manufacturing process, and specifications of this device are subject to change without notice. 6. Derived mathematically from one or more of the following directly measured parameters: fC, IL, 3 dB bandwidth, fc versus Tc , and Co. 7. Turnover temperature, To, is the temperature of maximum (or turnover) frequency, fo, The nominal center frequency at any case temperature , Tc, may be calculated from :f = fo [1-FTC (TO-TC) 2].Typically, oscillator To is 20 less than the specified resonator To. 8. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only . The capacitance Co is the measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground .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.
