Silicon Laboratories has a range of sub-GHz transceivers, the EZRadioPRO Si446x transceiver family which offer a transmit output power of +20dBm, sensitivity of -126dBm,  link budget of 146dB and RX adjacent channel selectivity of 58dB.

The transceivers also feature an antenna diversity algorithm developed to counteract the effects of multipath and fading, effectively doubling the wireless range in a multipath/fading environment.

Designed with continuous frequency coverage from 119 to 1050 MHz, the new Si446x transceivers support a number of advanced modulation techniques including 4GFSK, (G) FSK, GMSK and OOK with support for maximum data rates up to 1 Mbps (4GFSK).

The transceivers comply with the 802.15.4 d/g specification and the Wireless M-Bus protocol for smart utility networks. They are designed for emerging narrowband applications requiring compliance with FCC Part 90 Mask D, ARIB STD-T96/T67 and ETSI EN 300.

The Si446x products are the first transceivers to provide extended frequency coverage for new and emerging narrowband applications such as 151MHz multi-use radio service (MURS band) in the US, as well as the alternative 138MHz and 169MHz bands for the European market.

The Si446x transceivers achieve a 50 nA sleep/standby current with register retention. Transmit current specifications as low as 17mA at +10 dBm can be achieved for coin cell battery applications and 85 mA at +20 dBm for higher performance applications.
