Description

The RO2053 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro- vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at 310 MHz. The RO2053 is designed specifically for AM transmitters used in automotive-keyless-entry appli-cations operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.

Ideal for 310 MHz Transmitters Low Series Resistance Quartz Stability Rugged, Hermetic, Low-Profile TO39 Case Complies with Directive 2002/95/EC (RoHS)
