RFW122-M-PA ISM Transceiver Module with Power Amplifier
DESCRIPTION
The RFW122-M-PA is a small PCB module which
includes the RFW122-M module, besed on Vishay
RFWaves* RFW122 transceiver chipset, and a Power
Amplifier module. This module was created in order to
provide a solution for applications that have a need of
longer range than provided by the basic RFW122-M
19581
module.
The company’s products are covered by one or more
of the following:
Taiwan Patent No. 155994, Taiwan Patent No.
176767, USA Patent No. 6,535,545. Other patents
pending
The module consists of 2 main parts:
1. RFW122-M module - Based on Vishay RFWaves
RFW122 transceiver chipset
2. Carrier board which includes:
PA chip - A half-duplex RF power amplifier
module on chip with internal antenna
diversity support
A 9 pin application header for main board
connection
Tx/Rx switch
2 RF output ports
RF SAW filter
