MAX2820, MAX2820A, MAX2821, MAX2821A 2.4GHz 802.11b Zero-IF TransceiversThe MAX2820 MAX2820A and MAX2821 MAX2821A
single-chip zero-IF transceivers are designed for the
802.11b (11Mbps) applications operating in the
2.4GHz to 2.5GHz ISM band. The transceivers are
nearly identical, except the MAX2821 and MAX2821A
also provide a low-power shutdown mode and an Analog Voltage Reference output. The MAX2820A MAX2821A are cost-reduced versions, virtually identical
in pinout and performance to the MAX2820 MAX2821. The transceivers include all the circuitry
required to implement an 802.11b RF-to-baseband
transceiver solution, providing a fully integrated
receive path, transmit path, VCO frequency synthesis,
and baseband/control Interface Only a PA, RF Switch
RF BPF, and a small number of passive components are
needed to form the complete Radio front-end solution.
The ICs eliminate the need for external IF and baseband Filters by utilizing a direct-conversion Radio architecture and monolithic baseband Filters for both receiver and transmitter. They are specifically optimized for 802.11b (11Mbps CCK) applications. The baseband filtering and Rx and Tx signal paths support the CCK modulation scheme for BER = 10-5 at the required sensitivity levels. The devices are suitable for the full range of 802.11b data rates (1Mbps, 2Mbps, 5.5Mbps, and 11Mbps) and also the higher-rate 22Mbps PBCC standard. The MAX2820 and MAX2821 are available in a 7mm x 7mm 48-lead QFN package. The MAX2820 MAX2821 MAX2820A and MAX2821A are available in a 48-lead thin QFN package. By Maxim Integrated Products |
