The ECS-DR1-3180 is a one-port SAW resonator in a through-hole TO-39-3A package, designed for use in remote control and wireless security transmitters. It operates at a center frequency of 318.0 ± 0.075 MHz with a maximum insertion loss of 2.0 dB and an unloaded Q of 11,000. The device supports a 50 Ω loaded Q of 2,100, a frequency temperature coefficient of 0.037 ppm/°C, and a frequency aging of less than ±10 ppm per year. It operates reliably from -40 °C to +85 °C with a maximum DC voltage of 10 V between pins and a pin-to-pin static capacitance of 2.3 ± 0.3 pF. The component is Pb-free and RoHS compliant.
Known widely in the electrical and mechanical engineering industries as a surface wave equivalent to crystal resonators, SAW resonators are used for stable resonant frequency sources. SAW resonators operate at higher frequencies than other mechanical piezoelectric components, and they are often used in the manufacturing of radio transmitters, where tunability is not required. They’re ideal for other radio devices where channelization is not necessary, such as garage door openers, remote controls, short-range radio frequency links for computer peripherals and more. ECS Inc.’s SAW resonators meet industry standards for cell phones, keyless entry, digital satellite receivers and more.
ECS Inc. offers both through hole and surface mount SAW resonators from 310 MHz to 950 MHz. Surface mount SAW resonators can be installed without drilling into the board and thus are more efficient than through hole resonators. When through hole packaging is necessary, like in applications not migrated to surface-mount technology, ECS Inc. can supply SAW resonators, which tolerate more environmental stress than their surface mount counterparts.
