Microchip Technology, Inc. RF Transceiver Modules and Modems MICRF620Z TR

The MICRF620Z TR is a compact RF transceiver module designed for operation in the 434 MHz ISM band, measuring 11.5 x 14.1 mm. It supports frequency shift keying (FSK) modulation and is suitable for half-duplex, bidirectional RF links. The module features a fully programmable PLL frequency synthesizer, allowing for output power adjustment across seven levels. It includes a low noise amplifier, a zero intermediate frequency receiver, and integrated low-pass filters for effective channel filtering. Key functionalities include a digital bit synchronizer, a received signal strength indicator (RSSI), and power management features such as RX and TX power control and a power-down function. The MICRF620Z TR is surface mountable and comes in tape and reel packaging, making it suitable for automated assembly processes. Applications for this module include telemetry, remote metering, wireless controllers, and security systems. It operates within a temperature range of -20¬8C to +75¬8C, ensuring reliability in various environments.
