Copyright © Harris Corporation 1998 PRISM1KIT-EVAL DSSS PC Card Wireless LAN Description Introduction The PRISM1KIT-EVAL wireless LAN PC card is a complete wireless high speed modem utilizing the Harris PRISM™ Direct Sequence Spread Spectrum (DSSS) wireless transceiver chip set. The card is packaged in an open frame PCMCIA Type II extended coverset for evaluation access and a connector output for use in the laboratory. Evaluation kits include two cards, Microsoft® Windows® 95 software and documentation to get your WLAN evaluation started quickly. The PRISM1KIT- EVAL is not FCC approved as an intentional radiator and is intended for use with cabled connections only (30dB antenna port to antenna port attenuation recommended). An FCC experimental license is required while transmitting over the air with unapproved equipment. Please refer to the WLANKITPR1-KIT for an FCC-approved radio kit for wireless LAN evaluations. This application note details the RF and analog design of these cards. The physical layer (PHY) sections of these PC Cards are described in detail. The medium access control (MAC) section of the PC Cards will be described in detail in the pending AMD application note titled “Wireless LAN DSSS PC Card Reference Design” [1]. Figure 1 shows a block diagram of the reference radio design. This radio has been designed to conform to the draft IEEE 802.11 specification but does not include the antenna diversity selection.

Receive Processing Referring to the block diagram in Figure 1, the schematic on our web site [2], and the bill of materials in Appendix A, a single antenna is used. Up to two antennas are supported in the HFA3824A [3] Baseband Processor to implement diversity, countering the adverse effects of multipath fading. As space is at a premium in a PC Card environment, only one antenna is used. In an actual system implementation, if one can achieve diversity in at least one end of a link, such as at the access point where it is possible to achieve physical separation between diversity antennas, multipath performance will be improved.

The IF frequency is 280MHz, and low-side injection is used, thereby placing the received image 560MHz below the tuned channel. FL3 and FL6 also provide protection for the RF front-end from out of band interfering signals. The T/R switch is integrated in the HFA3925 [4] RF Power Amplifier (RFPA). The HFA3925 RFPA operates from the unregulated 5V PC Card supply. Following the T/R switch, the HFA3424 [5] Low Noise Amplifier (LNA) is used to set the receiver noise figure. The HFA3424 LNA operates from a regulated 3.5V…
