| HF868.35 868.35MHz SAW FILTER Approved by: Checked by: Issued by: SPECIFICATION PRODUCT: MODEL: SAW F I L T E R HF868.35 F-11 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 SAW Filter HF868.35 The HF868.35 is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter in a low-profile metal F-11 case designed to provide front-end selectivity in 868.350 MHz receivers. Receiver designs using this filter include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. 1.Package Dimension (F-11) Pin 1 4 23 Dimensions A B C D E F Configuration Input / Output Output / Input Case Ground Data (unit: mm) 11.00.3 4.50.3 3.20.3 0.450.1 5.00.5 2.540.2 2.Marking 3.Matching Circuit HF868.35 Color: Black or Blue 4.Typical Frequency Response Tel:+86-755-82973806 Fax:+86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com SAW Filter 5.Performance 5-1.Maximum Rating Rating CW RF Power Dissipation DC Voltage Between Any Two Pins Storage Temperature Range Operating Temperature Range P VDC Tstg TA Value +10 30V -40 to +85 -10 to +60 Unit dBm V HF868.35 5-2.Electronic Characteristics Characteristic Center Frequency (center frequency between 3dB points) Insertion Loss 3dB Pass band at fC -21.4MHz (Image) Rejection at fC -10.7MHz (LO) Ultimate Turnover Temperature Temperature Turnover Frequency Frequency Temperature Coefficient Frequency Aging Absolute Value during the First Year TO fO FTC |fA| fC IL BW3 35 25 -25 fc 0.032 10 -Minimum Typical 868.350 3.5 1,200 45 35 60 ---55 MHz ppm/ 2 Maximum Unit MHz 5.5 dB kHz dB ppm/yr CAUTION: Electrostatic Sensitive Device. Observe precautions for handling! C 2003. All Rights Reserved. 1. 2. The frequency fC is defined as the midpoint between the 3dB frequencies. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture that is connected to a 50 test system with VSWR 1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, fC. Note that insertion loss, bandwidth, and passband shape are dependent on the impedance matching component values and quality. Unless noted otherwise, specifications apply over the entire specified operating temperature range. 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. 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]. The specifications of this device are based on the test circuit shown above and subject to change or obsolescence without notice. All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale. 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.
