TQ9205

The TQ9205 is designed as one kind of monolithic transmit/receive amplifier function. The design of the TQ9203 provides a 2.4-2.5GHz ISM band,system noise figure for excellent sensitivity, and a good signal range with 10dBm input IP3. Its low current consumption, single +5V operation and small, plastic surface-mount package are ideally suited for cost-competitive, spacelimited and portable applications. In addition, two selectable RF inputs simplify implementation of "antenna diversity" in applications such as CDPD. The monolithic,internally matched design of the TQ9205 reduces development time,cost and level of RF expertise required to achieve a high-value 2.4 GHz RF subsystem solution.

Features of this TQ9205 are:(1)single-supply operation with power-down mode.No supply sequencing required;(2)+21 dBm power output;(3)integrated T/R switched and digital control logic;(4)24-pin SSOP compatible with PCMCIA card formats;(5)50 antenna and mixer ports.The TQ9205 can be used in general ISM-band spread-spectrum wireless communications,wireless local area networks and portable data terminals,remote monitoring.
