The ECS-D480A is a 480 MHz surface acoustic wave (SAW) filter in a thru-hole TO39-3A package, designed for satellite TV receivers. It has a center frequency range of 479.0 to 481.0 MHz, insertion loss of 19.5 to 21 dB, and a 3 dB pass band of 16.6 to 18.6 MHz. The filter provides minimum 38 dB attenuation at 430-461 MHz and 499-530 MHz, with amplitude ripple of 0.3 to 0.6 dB across 476-484 MHz. Group delay at 480 MHz is 281 ns, with group delay ripple of 11.5 to 18.0 ns over 471.5-488.5 MHz. Terminating impedances are 70 Ω//3.7 pF input and 280 Ω//2.5 pF output. It operates from -25°C to +85°C, with storage from -40°C to +85°C. The device is RoHS compliant.
As one of the world’s leaders in providing high-quality passive electronic components, ECS Inc. offers a large selection of surface acoustic wave (SAW) filters which operate by converting electrical energy into acoustic or mechanical energy on a piezoelectric material. At ECS Inc. SAW filters are available in both through hole and surface mount design (SMD) packages, with an extensive range of center frequencies. These SAW filters are available in both radio frequency (RF) and intermediate frequency (IF) and are designed for performance and longevity.
SAW filters are offered in a wide range of center frequencies, with standard through hole frequencies of 479.5 MHz and 480 MHz. The surface mount parts have standard frequencies of 947.5 MHz. Package sizes range from small (3.0 mm x 3.0 mm x 1.5 mm for the through hole) to large (9.5 mm x 9.5 mm x 3.5 mm for the surface mount option).
