F0443

Datasheet

Description

Features

The F0443 is a highly integrated 0.6GHz to 2.7GHz dual channel

RF digital variable gain amplifier designed for use in

diversity/MIMO receivers. The F0443 provides two independent

receiver paths each with 29.5dB typical maximum gain and 3.2dB

NF at 2.5GHz.

RF Frequency Range: 0.6GHz to 2.7GHz

Gain at 2.5GHz:

• 29.5dB typical max gain in non-bypass mode

• 10.9dB typical max gain in bypass mode

DSA Control

For each path, gain control is split into four separate digital step

attenuators: DSA0 provides 6dB of attenuation in a single step

using SPI/I3C control. Its counterpart, DSA1, also provides 6dB of

attenuation in a single step but it is programmed instead using an

external direct control pin. DSA2 yields 29dB of SPI/I3C-controlled

attenuation in 1dB steps, while its counterpart, DSA3, includes

18dB attenuation in 6dB steps programmed via two external control

pins. The device offers +39dBm nominal output IP3 at 2.5GHz

using 372mA total I_CCfor two active paths with a +5V supply

voltage.

• DSA0: Single 6dB step via SPI/I3C control

• DSA1: Single 6dB step via 1-bit external pin control

• DSA2: 29dB range in 1dB steps via SPI/I3C control

• DSA3: 18dB range in 6dB steps via 2-bit external pin

control

+39dBm OIP3 at 2.5GHz

NF at 2.5GHz

• 3.2dB typical in non-bypass mode

• 8.9dB typical in bypass mode

+19.7dBm OP1dB at 2.5GHz

I_CC= 372mA

The F0443 is packaged in a 7 × 7 mm, 48-LGA with 50Ω single-

ended RF input and RF output impedances for ease of integration

into the signal path.
