The MOBX222 from Mobix Labs is an Up/Down Frequency Converter IC that supports FR1 Baseband, C-Band (CBRS) and FR2 mmWave frequencies. It enables the use of input/output frequencies of DC – 800 MHz and 2.3 – 7 GHz IFs for up/down conversions to mmWave frequencies of 24.25 – 49 GHz. This IC includes a switch matrix that allows up/down conversions between 5G C-band and baseband signals for transmitting and receiving, and the FR1 Tx path integrates a high-linearity power amplifier and an RF power detector circuit. It is designed on 28 nm bulk CMOS process and provides device flexibility for various 5G applications by allowing for interoperability across frequency bands. The IC requires a single DC supply of 1.8 V for all device sections including Tx, Rx and SPI control. The baseband input of this IC uses a balanced quadrature configuration with a 100 Ω differential input impedance while all IF and mmWave inputs and outputs are single ended 50 Ω matched. It is available in a land-grid array (LGA) package with an operating temperature range from -40°C to +85°C.
