Transceiver chip requires only a few external components

18 May 2005 Telecoms, Datacoms, Wireless, IoT

Micrel's 32-pin MICRF506 transceiver operates from 410 MHz to 450 MHz and supports FSK modulation at data-rates up to 200 Kbps. Many functions are user-programmable including the frequency synthesizer, making the MICRF506 suitable for frequency hopping applications.

Reducing the overall size and lowering the total bill of materials (BOM) has been the primary objective in the design of the MICRF506, according to the manufacturer. Through high integration, the number of external components has been reduced to just a handful of capacitors, one inductor and a crystal.

The MICRF506 is designed to accommodate low cost, low accuracy crystals. To address this, Micrel added a frequency error estimator to determine frequency mismatch between communicating transceivers, and an internal crystal tuning mechanism to enable automated crystal tuning on-the-fly. The device also incorporates an internal clock recovery circuit to reduce the burden on its companion baseband device, enabling the use of a lower cost microcontroller.

This transceiver features high sensitivity, selectivity and transmit power so RF performance has not been sacrificed in the process of driving down BOM cost, says Micrel. In fact, by integrating the transmit/receive (T/R) switch there are no switch losses, making the system level RF performance even higher.

The MICRF506 operates on 2,0 to 2,5 V and has Rx sensitivity of -113 dBm. Transmit and receive current consumption is 21 and 12 mA resp. Max transmit power is 11 dBm, max baud rate is 200 Kbps, and the device comes in a 32-pin MLF package.
