The F0440 400MHz to 2700MHz dual RF digital variable 获得 amplifier (DVGA) is designed for use in receivers. The device provides two independent receiver paths each with 11.6dB typical maximum 获得 and 4.7dB noise figure in the low-band configuration designed to operate with a single +5V supply. For each path 获得 control is split into three separate attenuators; DSA0 is a single 6dB 步 using a single control pin, DSA1 includes 23dB SPI-controlled 获得 adjustment in 1dB 步s, and DSA2 includes 18dB attenuation in 6dB 步s controlled using two control pins. F0440 offers +40dBm nominal 输出IP3 using 245mA total ICC.
This device is 包裹d in a 6mm x 6 mm, 36-pin TQFN with 50? single-ended RF input and RF 输出阻抗s for ease of integration into the signal-path lineup for each of the two paths.

Evaluation Board for F0440 Dual Matched Broadband RF DVGA
The F0440EVB is a fully populated evaluation board which allows the customer to easily evaluate the F0440 Dual Matched Broadband RF DVGA. The attenuation setting may be set using the F0440's serial control input. Header pins on the evaluation board allow setting standby mode without off-board connections to the control inputs.
