Description The contains a power amplifier (PA), a low noise amplifier (LNA), and two SPDT switch. It is a 0-pins IC by 4 4mm -QFN package. RF input and output impedance of are 50Ω matched. Therefore, precious real estate of circuit board is saved when is used. Besides, there is one more precious advantage of. MCP03 and are pin-to-pin compatible. Compared with, MCP03 s maximum output power is 5dB higher but consumes around 50mA more of current. When longer communication range is critical in a different wireless communication market, the in the original circuit board could be replaced by MCP03 directly without modification of the original PCB. However, if this feature is desired, please layout the PCB based on MCP03 s data sheet. With the use of, it will offer convenience, flexibility and cost saving. Features RF input power of PA is adjustable for maximum linear performance of PA. 1.8dBm P1dB and 15.5dB gain for transmitting RF signal..db NF and 11.5dB gain for receiving RF signal. All PA, LNA and SPDT switch contained in a 0 pins 4 4mm -QFN package. Adjustable turn-on voltage levels. Applications Bluetooth..4 GHz ISM band application. Wireless phone. ZigBee.

Ports,, VB_LNA, and VB1 are used as on/off control as well as bias control for PA and LNA. Usually,, and VB1 are connected to TX_ON, and VB_LNA are connected to RX_ON. Both TX_ON and RX_ON are digital control signals that are provided by transceiver or base-band chip. When TX_ON outputs high, it indicates the system is in the transmitting mode. When RX_ON outputs high, it indicates the system is in the receiving mode. Resisters 300Ω and 4.7KΩ are for TX_ON and RX_ON that are operated at 3.3V. Their values need to be changed if different voltage level of TX_ON and RX_ON (such as 3.1V) are used. You may contact us for proper resister s values. MCP03 and are pin-to-pin compatible.
