The MAX2828/MAX2829 single-chip, RF transceiver ICs are designed specifically for OFDM 802.11 WLAN applications. The MAX2828 is designed for single-band 802.11a applications covering world-band frequencies of 4.9GHz to 5.875GHz. The MAX2829 is designed for dual-band 802.11a/g applications covering world-bands of 2.4GHz to 2.5GHz and 4.9GHz to 5.875GHz. The ICs include all circuitry required to implement the RF transceiver function, providing a fully integrated receive path, transmit path, VCO, frequency synthesizer, and baseband/ control interface. Only the PA, RF switches, RF bandpass filters (BPF), RF baluns, and a small number of passive components are needed to form the complete RF front-end solution.

Each IC completely eliminates the need for external SAW filters by implementing on-chip monolithic filters for both the receiver and transmitter. The baseband filtering and the Rx/Tx signal paths are optimized to meet the 802.11a/g IEEE® standards and cover the full range of the required data rates (6, 9, 12, 18, 24, 36, 48, and 54Mbps for OFDM; 1, 2, 5.5, and 11Mbps for CK/DSSS), at receiver sensitivity levels up to 10dB better than 802.11a/g standards. The MAX2828/MAX2829 transceivers are available in the small 56-pin, exposed paddle thin QFN package.

Applications

  • 2.4GHz/5GHz MIMO and Smart Antenna Systems
  • 4.9GHz Public Safety Radios
  • Single-/Dual-Band 802.11a/b/g Radios

Evaluation Kits for the MAX2828 and MAX2829

Features and Benefits

  • On-Board Line Drivers and Voltage Reference
  • 50Ω SMA and BNC Connectors on All RF and Baseband Ports
  • 3-Wire Serial Interface

Product Detail

The MAX2828/MAX2829 evaluation kits (EV kits) simplify the testing of the MAX2828/MAX2829. The EV kits provide 50Ω SMA connectors for all RF and baseband inputs and outputs. Differential-to-single-ended and single-ended-to-differential line drivers are provided to convert the differential I/Q baseband inputs and outputs of the MAX2828/MAX2829 to single-ended ports.

The EV kits simplify evaluation of the receive and transmit performance in the corresponding 802.11x bands.

Applications

  • 2.4GHz/5GHz MIMO and Smart Antenna Systems
  • 4.9GHz Public Safety Radios
  • Single-/Dual-Band 802.11a/b/g Radios

INTF3000 Interface Board for EV Kits Requiring SPI/Parallel to USB Interface

Features and Benefits

  • Parallel Port-to-USB Interface
  • Serial port interface (SPI) to USB Interface
  • Supports Wide Voltage Range: 2V — 5V
  • INTF2400 Connector Compatible with Old INTF2400 LPT Port Boards
  • Addressing Enables the Use of up to Four Boards on a Single PC

Product Detail

The INTF3000 interface board is designed to facilitate the interfacing of Maxim’s evaluation kit (EV) boards to any personal computer (PC) through the USB port.

There are three different connectors on the INTF3000 interface board available to communicate with the EV board: INTF2300, INTF2400, and DB25 (LPT) parallel connector. The INTF2400 connector is intended for new designs, while the INTF2300, INTF2400, and DB25 parallel connector can support legacy EV boards that are already configured for one of these types of interfaces. It must be noted that legacy EV boards that were designed to com- municate with the PC through DB25 parallel port must also have an updated control software which supports the INTF3000 interface board.

All three connectors on INTF3000 interface board sup- port logic levels from 2V to 5V. The INTF3000 requires no special driver installations on the host PC. The board connects to the PC with a standard USB cable.
