Chipset transceiver

Integration Associates has unveiled its next-generation EZRadio FSK (frequency shift keying) wireless chipsets, the IA4420 and IA4421 transceivers.

The transceivers enable bidirectional communication for low cost, high performance wireless applications in the consumer electronics, automotive, toy, home automation and building security markets.

The transceivers are software programmable and combine automatic antenna tuning technology in an integrated RF chipset to provide reliable connectivity while reducing materials.

In addition, it features extended battery life and enables the use of less expensive crystals and microcontrollers.

The transceiver is available in two versions: a low power amplifier and a high power amplifier.

IA4420: low power 4 dB device. Due to its high sensitivity, it has a limited range of 100+ m outdoors typical, and 40+ m indoors.

IA4421: high power 8 dB amplifier for longer distance; FCC and ETSI ISM bands: 315, 433, 868, 915 MHz; data rate: 256 Kbps maximum bit rate.

The wireless chipset family also includes the IA4220 low power transmitter, the IA4221 high power transmitter, and the IA4320 receiver.
