The F0448 is a 3.3GHz to 4.2GHz dual RF digital variable 获得 amplifier (DVGA) designed for use in receivers. This dual RF DVGA provides two independent receiver paths each with 13dB typical maximum 获得 and 6dB noise figure designed to operate with a single +5V supply. For each path, 获得 control is split into 3 separate attenuators; DSA0 a single 6dB 步 using a single control pin, DSA1 a 23dB SPI-controlled 获得 adjustment in 1dB 步s, and DSA2 includes 18dB attenuation in 6dB 步s controlled using two control pins. F0448 offers +37dBm nominal 输出IP3 using 220mA total ICC. This device is 包裹d in a 6mm x 6mm, 36-QFN with 50? single-ended RF input and RF 输出阻抗s for ease of integration.

Evaluation Board for F0448 Dual Matched Broadband RF DVGA
The F0448EVB is a fully populated evaluation board which allows the customer to easily evaluate the F0448 Dual Matched Broadband RF DVGA. The attenuation setting may be set using the F0448's serial control input. Header pins on the evaluation board allow setting standby mode without off-board connections to the control inputs.
The F0448EVS is a complete hardware and software solution that allows customers to digitally control the F0448EVB with the USB output on a computer. The kit includes the F0448EVB board, as well as a USB Digital Control Board and interface cables.
