RFM expands low-power RFIC line by with 300 – 510 MHz TRC105 transceiver


ESC Boston, Ma. – RF Monolithics, Inc. announced the expansion of its low-power short-range radio RFIC line with the addition of the new 300 MHz to 510 MHz TRC105 transceiver radio.

The TRC105 is designed for enabling two-way wireless communications in a wide range of applications. Applications include AMR (Automated Meter Reading), Medical (MICS), Home & Industrial Automation, Security Systems, Two-Way RKE (Remote Keyless Entry), Automobile Immobilizers, Asset Tracking Systems, Sports & Recreation Equipment, Low Power Two-Way Telemetry Systems, and Wireless Toys.

According to Larry Miller, RFM Director of Product Marketing for Short-Range Radio Products, the device is FHSS capable, multi-channel and are packaged in a 5 mm X 5 mm plastic package.

The TRC105 operates across the full 300 ” 510 MHz range and Development Kits are available in eight frequency bands: 303-307 MHz, 310-319 MHz, 342-348 MHz, 365-381 MHz, 382-398 MHz, 402-407 MHz, 416-436 MHz, and 447-451 MHz, whereas the TRC103 is available in three frequency bands: 863″870 MHz (ETSI), 902″928 MHz (FCC), and 950″960 MHz (Japan).

He said that because many apps require the radio to listen more than transmit, the TRC105,receiver current is 3.5 mA typical and can be reduced as low as 2.7 mA and as a Receiver Sensitivity at -112 dBm typical (FSK).

It is programmable Transmit Power up to +13 dBm and allows a companion microcontroller to sleep until data is received that requires processing. Transmit/Receive FIFO can be loaded/unloaded with radio in sleep mode, programmable TX/RX FIFO at 64 byte

It transmits at 32 kb/s OOK and 200 kb/s FSK to reduce transmitter on time and save power and using the RSSI in Receive mode, the Transmit power can be adjusted to maintain the data link and maximize power consumption.

The device pricing starts at $2.23 each at a minimum quantity of 3,000 units. Volume discounts are available. The TRC105 product line includes developer kits that are available for the major frequency ranges. The TRC105 developer kits are priced at $280 each and will be available by the end of October.
