Overview
MICRF507 470MHz to 510MHz Low-Power FSK Transceiver with +10dBm Power Amplifier General Description The MICRF507 is a fully-integrated FSK transceiver with +10dBm power amplifier and transmit/receive switch.
The device is targeted at automated meter reading (AMR) applications in the China Short Range Device (SRD) frequency band of 470MHz to 510MHz.
The device supports data rates up to 20kbps with PLL divider modulation and up to 200kbps with VCO modulation.
The receiver achieves a sensitivity of -113dBm at a data rate of 2.
4kbps while only consuming 12mA of supply current.
The integrated power amplifier (PA) delivers +10dBm of output power while only consuming 21.
5mA of supply current.
Power down supply current is a low 0.
2µA while retaining register information and a low 280µA in standby mode where only the crystal oscillator is enabled.
The receiver of the MICRF507 utilizes a Zero IF (ZIF) I/Q architecture, integrating a low-noise amplifier (LNA) with bypass mode, I/Q quadrature m...
