Block Diagram: SDI S | XTAL SDO P SCLK LNA nSEL I RF RF RF MATCHING ANT Switch CIRCUIT IC PA DIO 0 - 5 Battery Voltage Detector ~~Je~~ RX SWITCH TX SWITCH Application Resources: The LAMBDA68 is a ready to use application of the Semtech LLCC68. Access to the programming and configuration of Semtech LLCC68 Transceiver are via the module SPI interface. The LAMBDA68 has been developed with Semtech to provide a low cost platform application of the RF Transceiver IC. This offers optimal design realisation and easy integration within the end application. The most important aspect of any RF Module is to maximise the performance of the transceiver at the external module pads. In particular the impedance matching network which is the most sensitive section of the RF module design. In order to maximise signal propagation to the external pad of the module, a specific layout is required which is not (usually) the smallest physical size (beware of small RF modules!). Many RF Module manufacturers simply reproduce the IC manufacturers data characteristics where in practice the Module RF performance is considerably lower. We have measured the conducted power transmitted from the LAMBDA68 ufl connector at +22dBm, which demonstrates the efficiency of the LAMBDA68 module. To ensure that the latest details in programming this device are offered, we have not included the LLCC68 programming information in this document. You can find the datasheet at the link below: LLCC68 Datasheet Programming, configuration and further resource data including; LoRa Calculator: fast evaluation of link budget, time on air and energy consumption.

The above schematic shows an easy interface to a PIC Microcontroller. 

Walk Test application 

Also available is the source code used to carry out a simple range test. 

In order to use this two application boards are required, one acts as a beacon transmitter, the other as the beacon receiver. The TX board will illuminate the GREEN LED when transmitting and the Receiver will illuminate the RED LED when RECEIVING. 

The Transmitter board transmits an RF beacon every second (Green LED flashes to indicate transmission). 

This enables a one man range test, by placing either board in a fixed location and monitoring the beacon signals.

## LAMBDA68 LoRa Transceiver 

## Controlling the Transmit / Receive RF Switch: 

The LAMBDA68 has two inputs to control the onboard RF Switch which connects the impedance matching network / antenna to the  Transmit / Receive circuit. 

There are two connections in order to provide three states (TX, TX, Disconnected) 

Although this requires two I/O Lines this can be reduced to one by using a simple inverting Transistor as shown below, 

The TX Switch input can be controlled from the host Micro or, as in the example below by using one of the DIO lines from the LAMBDA62 module as an output to control.

## Note: 

Set Regulator Mode should be set to 0 (LDO Mode) 

The hardware design uses the internal LDO regulator (not the SMPS DC-DC), we chose not to implement the internal BUCK regulator because in our experience, when a battery is reaching end of life the voltage it provides starts to drop and then avalanches in a non linear curve in a short time. 

It is only at this stage that the SMPS provides a benefit over and above the LDO regulator, and considering the cost of the large inductor the SMPS requires its not justified for a marginal extension in time the circuit obtains.
