1. Overview
The A110LR09A and A110LR09C are surface mount modules
– each with an integrated crystal,
internal voltage regulator, matching circuitry and filtering. The A110LR09A has an integral
antenna, whereas the A110LR09C utilizes an external antenna through a U.FL connector (see
Table
1
). The modules operate in the European 868
– 870MHz and US 902 – 928MHz ISM
bands and are ideal for achieving low power wireless connectivity without having to deal with
extensive RF, antenna design and regulatory compliance, allowing quick time to market. The
modules are 100% tested to provide consistent performance.
The A110LR09A and A110LR09C have received regulatory approvals for modular devices in
Europe and in the US. The modular approval allows the OEM or end user to place either an
A110LR09A or an A110LR09C with an approved antenna inside a finished product without
having to perform costly regulatory testing for an intentional radiator. Section 2 has information
on the requirements for the end user/integrator must fulfill to use the modules without intentional
radiator regulatory testing. The receiver section of the modules has been evaluated and
approved as Category II receiver for use in Europe.
The A110LR09A and A110LR09C are based on the CC110L transceiver IC from Texas
Instruments. All control lines for the transceiver are provided at module level for full control of its
operation. Please see the CC110L data sheet (www.ti.com) for how to control the modules.
Please see section 2.5 for the recommended register settings to achieve optimal performance
and regulatory compliance.
The A110LR09A measure 9x16x2.5mm and A110LR09C measures 9x12x2.5mm. The modules
are footprint compatible with each other.
1.1.
A110LR09A
The A110LR09A has an integral antenna, providing high efficiency and near omni-directional
radiation pattern. This approach offers the lowest system cost when the application allows
collocation of radio and antenna.
1.2.
A110LR09C
The A110LR09C has a compact antenna connector that allows for locating the antenna away
from the module due to form/function or in order to exit a metal enclosure, see figure 6
– 9 for
more information on antenna location and enclosure considerations.
