Product overview Layout information
The A20737A is a high-performance, FCC & IC certified and
ETSI-compliant module featuring Bluetooth Smart technology
that incorporates the Broadcom BCM20737 SOC in one of the
industrys smallest packages (11 x 13 x 2.5 mm). The module
incorporates an EEPROM, 24MHz crystal and the required RF
matching and filtering for regulatory compliance. The modules
operate in the global unlicensed 2.4GHz ISM/SRD frequency
band. These radio modules are ideal for achieving low power
wireless connectivity without having to deal with extensive
protocol, RF design and regulatory compliance, allowing quick
time to market. The modules are 100% RF-tested to provide
consistent performance.
The A20737A has a RoHS-compliant ENIG finish and is
packaged in 36-piece matrix trays or on 500-piece tape & reel for
high-volume automated manufacturing.
