Frequently asked questions

What is the TRX BF/01?: It is a complete 16RX + 16TX beam forming RF transceiver supporting the frequency band 57-71GHz.
What is the architecture used in the TRX BF/01?: It is a Zero-IF topology ie 16 RF in/out and analog base band I/Q in/out.
What is the main targeted application for TRX BF/01?: The Transceiver is targeting data and telecommunication infrastructure solutions for unlicensed 5G mm-wave use cases.
Does the TRX BF/01 have any internal calibration routines?: The TRX BF/01 includes support for DC offset, LO leakage and IQ calibration. It includes an auxiliary ADC, supporting various external functions, e.g. power and temperature measurements as well as production test support.
What is the size of the TRX BF/01 package?: 1.26×1.26cm.
TRX BF/01: The beam book states 64 phase vectors can be stored. Can you describe what each vector consists of and the process of importing our own?: Regarding the beambook we will give you a short explanation for now, hopefully soon we can provide you with a user manual describing this in more details: The beam book file consists of a matrix of the form 16 columns and 64 rows. Each column contains information to the corresponding antenna how the phase shifts should stand (note that the beambook is reversed ie column 0 controls antenna patch 16) and each row contains one of 64 possible beams that the memories may contain. Each cell can thus have values from 0x0000 to 0x3F3F.
What packaging technology does TRX BF/01 use?: It uses embedded wafer level ball grid array (eWLB) package.
What is the TRX BF/02?: It is a complete 16RX + 16TX beam forming RF transceiver supporting the frequency band 24-29.5 GHz.
What is the architecture used in TRX BF/02?: It is a Zero-IF topology ie 16 RF in/out and analog base band I/Q in/out.

What packaging technology does TRX BF/02 use?: It uses embedded wafer level ball grid array (eWLB) package.
How many polarisations can the chip AFE VM 2Q 275/295 support?: It can support two polarisations.
How much power does the chip AFE VM 2Q 275/295 consume?: Please contact [email protected] for further assistance.
What packaging technology does the chip AFE VM 2Q 275/295 use?: It uses Wafer-level chip scale packaging (WL-CSP) technology.
Does the chip AFE VM 2Q 275/295 have it’s own clock synthesiser, up/down converter?: No. This is an analog beamformer IC which requires signals at 5G NR frequencies (24 to 29 GHz).
Do I need to sign an NDA to get the datasheet for AFE VM 2Q 275/295 ?: Yes.
Does one chip AFE VM 2Q 275/295 cover the whole 5G NR frequency range from 24.25 to 29.5 GHz?: No. Two chips are needed for this. AFEVM2Q275 covers 24.25-27.5 GHz and AFEVM2Q295 covers 26.5-29.5 GHz.
