Key benefits Provides a precise center frequency of 137.5 MHz for dedicated RF designs, enabling targeted signal conditioning or filtering. Compact footprint (42.3 mm by 8.8 mm, excluding the connector) supports spaceconstrained assemblies. Lightweight at 10 grams, aiding easy mounting and minimal impact on overall device weight. Lowvoltage operation (4.5–5 V) compatible with common 5 V system configurations. Connector not included, allowing flexible choice of mating interface to suit your design. Specifications Center frequency: 137.5 MHz Size: 42.3 mm x 8.8 mm (excluding connector) Weight: 10 grams Voltage: 4.5–5 V Note: Connector is not included; plan for your preferred mating interface. Use scenarios In a compact RF frontend or transceiver module that requires a fixed 137.5 MHz reference or filter element. In a laboratory test bench or prototype setup for validating 137.5 MHz signal paths and performance. In fielddeployed equipment such as telemetry or lowpower communication devices that operate around 137.5 MHz and benefit from a dedicated fixedfrequency component.
