| HB217.25 217.25MHz TWO-Port SAW Resonator Approved by: Checked by: Issued by: SPECIFICATION PRODUCT: MODEL: SAW RESONATOR HB217.25 TO-39 HOPE MICROELECTRONICS CO.,LIMITED Tel:+86-755-82973806 Fax:+86-755-82973550 E-mail: sales@hoperf.com Page 1 of 3 http://www.hoperf.com Two-port SAW Resonator HB217.25 The HB217.25 is a two-port, 180 surface-acoustic-wave (SAW) resonator in a low-profile metal TO-39 case. It provides reliable, fundamental-mode, quartz frequency stabilization i.e. in transmitters or local oscillators operating at 217.250 MHz. 1.Package Dimension (TO-39) Pin 1 2 3 Dimension A B C D E Configuration Input / Output Output / Input Case Ground Data (unit: mm) 9.300.20 5.080.10 3.400.20 30.2050.20 0.450.20 2.Marking 3.Equivalent LC Model and Test Circuit HB217.25 Color: Black or Blue 4.Typical Application Circuits 1) Low-Power Transmitter Application 2) 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 Two-port SAW Resonator 7.Performance 7-1.Maximum Ratings Rating CW RF Power Dissipation DC Voltage Between Any Two Pins Storage Temperature Range Operating Temperature Range P VDC Tstg TA HB217.25 Value 10 30 -40 to +85 -10 to +60 Unit dBm V 7-2.Electronic Characteristics Characteristic Center Frequency (+25) Insertion Loss Unloaded Q Quality Factor 50 Loaded Q Turnover Temperature Temperature Stability Turnover Frequency Frequency Temperature Coefficient Frequency Aging Absolute Value during the First Year Absolute Frequency Tolerance from 217.250 MHz Sym fC fC IL QU QL TO fO FTC |fA| Minimum 217.100 Typical Maximum 217.400 Unit MHz kHz 150 4.5 14,820 6,000 25 fc 0.032 10 1.0 55 6.0 dB kHz ppm/2 ppm/yr M DC Insulation Resistance Between Any Two Pins Motional Resistance RF Equivalent RLC Model Motional Inductance Motional Capacitance Shunt Static Capacitance RM LM CM CO 68 738.8242 0.7271 1.7 2.0 99.5 H fF 2.3 pF CAUTION: Electrostatic Sensitive Device. Observe precautions for handling! C 1. 2003. All Rights Reserved. The 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. 2. Unless noted otherwise, case temperature TC = +25C2C. 3. 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 in subsequent years. 4. Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f0. The nominal frequency at any case temperature, TC, may be calculated from: f = f0 [1 - FTC (T0 - TC)2]. Typically, oscillator T0 is 20 less than the specified resonator T0. 5. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance C0 is the measured static (nonmotional) capacitance between either Pin 1 and ground or Pin 2 and ground. The measurement includes case parasitic capacitance. 6. Derived mathematically from one or more of the following directly measured parameters: fC, IL, 3 dB bandwidth, fC versus TC, and C0. 7. The specifications of this device are based on the test circuit shown above and subject to change or obsolescence without notice. 8. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufacturer. 9. Our liability is only assumed for the Surface Acoustic Wave (SAW) component(s) per se, not for applications, processes and circuits implemented within components or assemblies. 10.
