| HF433E 433MHz SAW Filter Approved by: Checked by: Issued by: SPECIFICATION PRODUCT: MODEL: SAW F I L T E R HF433E 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 SAW Filter HF433E The HF433E is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter in a low-profile metal TO-39 case designed to provide front-end selectivity in 433.920 MHz receivers. Receiver designs using this filter include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. 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 30.20 50.20 0.450.20 2.Marking 3.Test Circuit HF433E 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 Ratings Rating Input Power Level DC Voltage Storage Temperature Range Operating Temperature Range Pin VDC Tstg TA Value 10 0 -45 to +120 -45 to +120 Unit dBm V HF433E 5-2.Electronic Characteristics Reference temperature: Characteristic Center Frequency (center frequency between 3dB points) Insertion Loss 433.80 .... 434.12 MHz 3dB Pass bandwidth (relative to IL) Pass band (relative to IL) 433.76 .... 434.08 MHz 433.74 .... 434.10 MHz 433.68 .... 434.16 MHz Relative attenuation (relative to IL) 10.00 .... 414.00 MHz 414.00 .... 428.00 MHz 428.00 .... 432.84 MHz 434.92 .... 442.00 MHz 442.00 .... 550.00 MHz 550.00....1000.00 MHz BW3 fC IL TA = -45 .... +95 C Minimum Typical 433.920 -670 ---45 35 15 10 35 45 2.0 730 1.0 1.0 1.5 50 40 20 15 40 50 4.0 790 2.0 3.0 6.0 ------Maximum Units MHz dB kHz dB dB dB dB dB dB dB dB dB 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. 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.
