The ECS-SDR1 series is a surface-mount SAW resonator designed for transmitter applications, offering center frequencies at 315.0 MHz, 418.0 MHz, and 433.9 MHz with a frequency tolerance of ±75 kHz. It features an ultra-miniature SMD package, operates from -40°C to +85°C, and meets RoHS compliance. The device has an insertion loss of up to 2.0 dB, a unloaded Q of up to 11,400, and a shunt capacitance of 1.7 to 2.9 pF. Pin configuration includes input on pin 2, output on pin 6, and grounds on pins 4 and 8, with no connections on other pins. The solder profile allows a peak temperature of +260°C for up to 10 seconds, with MSL 1 qualification and gold lead finish.
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.
