HIGH PERFORMANCE RF MODULE RXM-418/433-RM RM SERIES RECEIVER MODULE DATA GUIDE DESCRIPTION: The LINX RM Series module incorporates an ultra-sensitive, SAW-based, doubleconversion FM superheterodyne receiver. When paired with the LINX RM Series transmitter module the units create a highly reliable RF link capable of transferring analogue or high-speed digital data at distances in excess of 500 ft. Like all Linx Package Outline modules, the RM Series needs no production tuning or adjustment and requires no external RF components except an antenna . Observing simple design rules, the module is easily integrated even by engineers lacking previous RF experience. FEATURE HIGHLIGHTS: s Compact SIP-style package s No production tuning or setup s Precision SAW-controlled FM reception s Selective double-conversion superhet design s High sensitivity for superior range s Supports high data rates up to 10 Kbps s Wide supply range vDC s Carrier detect & AF outputs s Low power consumption 14mA s Wide temperature range APPLICATIONS INCLUDE: s Remote Control / Access Control s Remote Monitoring / Telemetry s Medical Alert s Remote Industrial Process Monitoring s Periodic Data Transfer s Lighting Control s Garage/Gate Openers s Security / Fire Alarms s Wire Elimination ORDERING INFORMATION PART # MDEV-418-RM Evaluation Kit 418 MHz MDEV-433-RM Evaluation Kit 433 MHz TXM-418-RM- Transmitter 418 MHz RXM-418-RM- Receiver 418 MHz TXM-433-RM- Transmitter 433 MHz RXM-433-RM- Receiver 433 MHz ** Insert TB for Tube Packaging MODULE DESCRIPTION figure 1 Overall block Diagram THE SAW-BASED DESIGN ADVANTAGE The SAW Surface Acoustic Wave device provides a highly accurate frequency source with excellent immunity to frequency shift due to age or temperature.

THE SAW-BASED DESIGN ADVANTAGE

The SAW Surface Acoustic Wave device provides a highly accurate frequency source with excellent immunity to frequency shift due to age or temperature. The use of a SAW device on both the transmitter and receiver modules allows the receiver’s pass opening to be quite narrow, resulting in outstanding sensitivity and greater immunity to interfering signals. As an additional benefit, the SAW device is manufactured to resonate at a precise frequency, thus eliminating production tuning and lowering parts count.The SAW device, in combination with advanced design and manufacturing techniques, has made it possible to reduce the size and cost of an RF link, while enhancing its performance to a level rivaling far more complex and costly systems. The end user benefits from improved product range and reliability and the OEM manufacturer from lower cost and simpler manufacturing procedures.

PHYSICAL PACKAGING

The receiver is packaged as a hybrid SIP module with five pins spaced in. on center.The SIP package allows easy accommodation of both horizontal and vertical mounting requirements into a highly compact package. Its leaded design allows for easy prototyping and simple integration into through-hole and surfacemount designs. If the module will be bent and laid flush on the circuit board, it is suggested that a pad of silicon or other adhesive be used to hold it in place.

PIN DESCRIPTION

Pin 1

RF IN

The receiver antenna connects to this input.It is AC-coupled and has nominal RF
impedance of

Pin 2 & 4 GROUND This pin should be connected to a common groundplane.

Pin 3

DETECT

This pin may be used as described in this manual to derive an indication of when
a signal is being received. In combination with simple external circuits the pin is
useful for qualifying data and implementing power-save functions If the detect
function is not being used, a 10 pull up to pin 5 Vcc should be connected.

Pin 5

Positive supply of 4 to 9 volts. The supply must be clean <20 mV pp stable and
free of high-frequency digital noise. A supply filter is recommended unless the
module is driven from its own regulated supply or battery.

Pin 6

AF ANALOG OUTPUT

This is the FM demodulator output. It has a standing DC bias of approximately 2
volts and may be used to recover analog signals such as audio or tones. Load
impedance as low as 2 and up to 100 pF can be driven.

Pin 7

DATA DIGITAL OUTPUT

This digital output from the internal data slicer is a squared version of the signal
on pin 6 AF . This signal is used to interface with external digital decoders, or
logic devices such as a microprocessor. The output recreates the digital input to
the transmitter. Load impedance as low as 1 and up to 1 nF can be driven.
