This family includes high performance radios covering several RF bands used world-wide for remote control applications. They are built around a common architecture, and present a uniform host interface definition. The host interface is used for data communication and radio configuration. 1.2 SCOPE This document describes the host interface signal definitions, timings, operation mode, available functionalities, and provide details about its integration to Unity products. This document does not cover RF specifications or power supply specifications. 1.3 APPLICABILITY This description applies to all 2PCA-8694-Dxxx. 1.4 ACRONYMS, ABBREVIATIONS Acronyms CTS - Clear to Send.

The figure below shows a high-level block diagram of the radio. Figure 2.1 LRM2 high-level block diagram The U7 is located between the host interface and the RF interface, providing decoupling between host and RF interface. The microprocess has sufficient buffer space for one telegram. As shown later, telegram processing is defined to minimize delays, so to provide a transparent-like behavior. The transceiver is intended to be powered using an externally provided 12VDC supply. The overall current consumption @ 12VDC in RX mode is about 110mA. The Transmit section was designed to provide a nominal output power of +27dBm into a 50 ohm load. The overall current consumption for TX is an additional 450mA, resulting in a total current during TX of about 560mA. The RF section is contained in a shielded enclosure that has openings for four 50ohm SMB connections:

1. ANT1 --- RX input 1 2. ANT2 --- RX input 2 3. ANT3 --- RX input 3 4. TX OUT Cattron proprietary and confidential Page 9 of 15 9S02-8694-D001 Revision: A, Approved 2PCA-8694-Dxxx Radio Module 9S02-8694-D001 In addition to these there are openings for visual observation of the PLL Lock status, as well as two alignment points, one adjusting the 2nd RX LO frequency and adjusting the RX Quadrature detector. There is no need to trim the TX and the RX front end sections, The following sections will contain a detailed description of the different circuit blocks pertaining to the transceiver. 2.2 POWER SUPPLIES AND REGULATORS A nominal external 12VDC is supplied to the assembly using P101 pin 7 (positive) and pin 10 (negative). This input is directly fed to U113 (LT1961EMS8-5#PBF) and to U5004 (KA7809). These two LDOs could accept 12VDC+/-15% . The +5VDC output of U113 is used to supply the digital section as well as the RX DATA buffer and shaping amplifiers and the modulation active filter chain, this +5V supply voltage feeds also a 2.7V voltage regulator to supply the ADC reference voltage for the CPU (U6001 ADP160AUJZ-2.7). The +9VDC output is used to feed the RF RX regulator MIC5216-5.0 (U4) which provides +5V to the synthesizer and RX chain. The +9V output is also used to supply regulator U52002 (KA7805) which is powering the TX Driver and PA stages. 2.3 DATA COMMUNICATION MODEL & DEFINITIONS The communication model defines some of the terminology used in the radio. Figure 2.2 - Data communication model

- The Radio Module is used to communicate telegrams between hosts. In Unity context, hosts are OCU and MCU CPU boards. The radio has two interfaces: a Host Interface and a RF Interface.

- Transmit and Received Telegrams are relayed through the radio Host Data Buffer. This buffer is capable to hold only one telegram at a time. The purpose of this buffer is to relax host timings requirements, and to allow decoupling between Host Interface and RF Interface data rates. Cattron proprietary and confidential Page 10 of 15 9S02-8694-D001 Revision: A, Approved 2PCA-8694-Dxxx Radio Module 9S02-8694-D001

- Telegrams sent/received on the Host Interface and RF interface are encapsulated into frames to improve synchronization.

- The radio does not perform any processing on the telegrams content; it controls only the frames overhead. 2.4 Frequency Reference and Phase Locked Loop:

The overall RF system frequency reference is provided by a 14.4 MHz VCTCXO (designator Y4). The synthesizer uses an external VCO (designator U6) that is tunable from 425 to 475 MHZ. The nominal RF output level of the VCO is nominally between +2 and +6 dBm into 50 ohms. The RF output of the VCO is subsequently split using resistive dividers into:

1. RF Sample input for the PLL 2. 1st RX Mixer LO input 3. TX signal input to the TX Amplifier chain. 2.5 Receiver Section:

The RF input to the Receive section is provide using one of the existing ANT1, 2, 3 input, these are selected using signals provided by the Microcontroller (designator U5). The received signal is the routed to a UHF SAW filter FL1 that has a width of about 20MHz and is centered in one of the designated RX bands:

Low Band 406 to 425 MHz Mid Band 425 to 447 MHz High Band 447 to 475 MHz These filters are installed depending on the RX Band variants that are being used. The Local Oscillator input is supplied by an output of the splitter mentioned above referring to the VCO. The 21.4MHz mixer signal output is filtered using a crystal Filter (designator Y1), the BW of this filter is selected depending on the product variant built (either a narrow or a wide band version). After filtering the 21.4 MHz signal is routed to an FM IC that performs an additional frequency down-conversion to 455kHz and provides a second mixer and 2nd LO oscillator using and externally supplied crystal (designator Y2). Cattron proprietary and confidential Page 11 of 15 9S02-8694-D001 Revision: A, Approved 2PCA-8694-Dxxx Radio Module 9S02-8694-D001 The FM IC SA605 (designator U2) additionally provides limiting IF gain and quadrature detection as well as having outputs for RSSI monitoring besides the demodulated signal. The second IF Filtering is provided using two 455kHz Ceramic Filters 455FU (455DU) (designators FL3 and FL4).
