| Crystal Filter 45-90 MHz-Series MCF n Features Because this MCF has a built-in transformer, it is possible to match an input/output circuit with various impedance values. l Compact and light. l Stable temperature characteristics. l This product can be manufactured according to your requested terminating impedance value. l Because it has already been completely adjusted, no adjustment is needed before use. l It can be manufactured with a wide frequency band. Caution * Because it has a non-enclosed structure, it cannot be washed. Type: with a Built-in Transformer n Specifications Model Nominal frequency Channel spacing 3 dB passband width Stop bandwidth Ripple Insertion loss (insertion attenuation) Guaranteed attenuation Spurious characteristics Terminating impedance Operating temperature range Package type Code for placing an order 45NE7.5BB-45MFN15-840 45NE15BC-45MFN15-841 30 dB min. 20 dB min. 45NE7.5BB 45MH z 12.5k Hz 3.75k Hz 12.5 kHz max. at 25 dB 45NE15BC 45MH z 25k Hz 7.5k Hz 25 kHz max. at 30 dB 70NE7.5B 70MH z 12.5k Hz 3.75k Hz 12.5 kHz max. at 25 dB 2 dB max. 6 dB max. 70 dB min. at 910 kHz 30 dB min. 20 dB min. 30 dB min. 20 dB min. 70NE15B 70MH z 25k Hz 7.5k Hz 25 kHz max. at 30 dB 90NE7.5BB 90MH z 12.5k Hz 3.75k Hz 12.5 kHz max. at 25 dB 90NE15BC 90MH z 25k Hz 7.5k Hz 25 kHz max. at 30 dB 50//0pF -20 to +70C D-168 70NE7.5B-70MFN15-842 70NE15B-70MFN15-843 90NE7.5BB-90MFN15-844 90NE15BC-90MFN15-845 n Dimensions D-168 n Characteristics mm ATT.(dB) 10 20 30 40 50 60 (A) Channel spacing 12.5kHz 10.5max 41 70 80 (B) 4min 1.50.5 4-0.8max (A) (B) -25 -1.0 -20 -0.8 -15 -0.6 -10 -0.4 -5 -0.2 0 5 0.2 10 0.4 15 0.6 20 0.8 25 (kHz) 1.0 (MHz) Channel spacing 25kHz ATT.(dB) 10 20 30 40 50 60 70 (A) IN OUT 4.6 3.5 10.5max GND 11.60.5 18.5max GND 80 90 (B) (A) (B) -50 -1.0 -40 -0.8 -30 -0.6 -20 -0.4 -10 -0.2 0 10 0.2 20 0.4 30 0.6 40 0.8 50 (kHz) 1.0 (MHz) cf20_071102_45-90MCF_e1 |
