1. Overview
The A1101R09A and A1101R09C are surface mount modules – each with an integrated crystal,
internal voltage regulator, matching circuitry and filtering. The A1101R09A has an integral
antenna, whereas the A1101R09C utilizes an external antenna through a U.FL connector (see
Table 2). The modules operate in the US 902 – 928MHz ISM band 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 A1101R09A and A1101R09C have received regulatory approvals for modular devices in
the United States (FCC) and Canada under Industry Canada (IC) Radio Standards Specification
(RSS) RSS-210 and RSS-Gen. The modular approval allows the OEM or end user to place
either an A1101R09A or an A1101R09C with an approved antenna inside a finished product
without having to perform costly regulatory testing for an intentional radiator. Section 2.3 has
information on the requirements for the end user/integrator must fulfill to use the modules
without intentional radiator regulatory testing.
The A1101R09A and A1101R09C are based on the CC1101 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 CC1101 data sheet (www.ti.com) for how to control the modules.
The A1101R09A measure 9x16x2.5mm and A1101R09C measures 9x12x2.5mm. The modules
are footprint compatible with each other.
1.1.
A1101R09A
The A1101R09A 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.
A1101R09C
The A1101R09C 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 7

Figure 10
for more information on antenna location and enclosure considerations.
