New Integrated Circuit Designed to Support FR1 BB, CBRS and C-Band alongside of FR2 mmWave in 28nm Bulk CMOS Will Be Previewed at Mobile World Congress in Barcelona.
Mobix Labs Inc., a global connectivity solutions provider for next-generation wireless mmWave 5G and wired high bandwidth cable networks, introduced its MOBX222, the company’s latest up/down frequency converter that is being offered as a standalone product or part of a complete True5G chipset with beamformers and synthesizers. The product was designed in collaboration with Airgain, Inc. , a leading provider of wireless connectivity solutions.
The MOBX222 is an integrated circuit designed to provide device flexibility for various by allowing for interoperability across frequency bands. It is baseband agnostic and includes 2-Channel 5GNR mmWave, Frequency Range 2 (FR2) and FR1.

Some of the features include:
- Designed in 28 nanometer bulk CMOS
- Designed with a land grid array (LGA) package for optimal thermal performance over an ambient operating temperature range of -40 oC to +85 oC
- Supports frequency bands n257 through n262, CBRS and C-band spectrum (3.3-4.2GHz)
- Is a true single-chip, single-die solution
- Has a single 1.8 Vdc supply for all device sections including Tx, Rx and SPI control
- Enables the use of input/output frequencies of DC-800MHz and 2.3-7GHz IFs for up/down conversions to mmWave frequencies of 24.25-49GHz
- The switch matrix allows up/down conversions between 5G C-band and baseband signals for transmitting and receiving
- The circuit’s FR1 Tx path integrates a high-linearity power amplifier and a RF power detector circuit
- The baseband input uses a balanced quadrature configuration with a 100Ω differential input impedance while all IF and mmWave inputs and outputs are single ended 50Ω matched.
“Enhancing 5G network coverage and improving end user experience is the focus of our product development,” said Dr. Ali Sadri, Chief Technology officer at Airgain. “We believe our collaboration with Mobix Labs in defining the MOBX222™ frequency converter can simplify enhanced features by adding flexibility to the design of 5G products.”
