1 Introduction

The purpose and scope of this document is to provide the specifications for the RF112

1x4 ISM transceiver.

The RF112 Transceiver consists of three RF sub-systems; one dual band 1x2 MIMO

transceiver, denoted TRX, one dual band observation receiver, denoted RO1, and one

high band observation receiver, denoted RO2, together with a crystal oscillator and a

digital core which is used to control the transceiver, and interfaces. The TRX, RO1, and

RO2 sub-systems operate independently. The dual band units can be configured to work

in either low band or high band, but since they share synthesizer, channel filters and

analog baseband interfaces the bands cannot be used concurrently.

Figure 1. RF112 Transceiver Simplified model

The RF112 Transceiver uses a direct conversion architecture for both RX and TX. The

chip has independent synthesizers for each sub-system driven from a common reference.

The frequency reference can be a 40 MHz crystal or external oscillator. The input

reference is multiplied internally by 4 and can be routed to an output differential driver

for use as a low jitter 160 MHz frequency reference by other devices in the system. The
