Product Brief March 2001 W7020 Radio Module Features Description + Complete RF solution, compliant with Bluetooth* specification version 1.0B + Highly integrated module including RF transceiver IC, antenna filter, and transmit/receive baluns + 0 dBm, typical, output power at 50 Ω + 2.7 V operation enabling long battery life + 3.2 kHz low-power, idle-mode clock + Digital receive signal strength indicator (RSSI) + Small-outline module ceramic land grid array (MCLGA) package (9.7 mm x 14.0 mm x 1.6 mm) + Evaluation kit available, including W7020 evaluation board, USB transceiver interface board, and PC control software The W7020 radio module is a short-range microwavefrequency radio transceiver for Bluetooth links. It operates in the globally available 2.4 GHz to 2.5 GHz ISM band. The radio is based on a bipolar complementary metal-oxide semiconductor (BiCMOS) RF integrated circuit. The antenna filter and the RX and TX baluns are all integrated into the radio subsystem (see Figure 1). As illustrated in Figure 2, the radio module requires only an external antenna connected through a 50 Ω characteristic impedance line and a 13 MHz crystal or reference clock signal to enable Bluetooth radio communication links. It interfaces to a baseband controller through the serial interface bus and separate strobe signals to create a complete Bluetooth hardware solution.
