优势和特点

Integration of upconverter, downconverter and LO chain with multiplier in one chip
CMOS up/downconverter with industry leading efficiency and linear Pout with 5G NR
RF input/output frequency range: 37 GHz to 48 GHz
Integrated RF switch
Supports both half / full duplex operation
Two operation modes for both up and downconverter configurations:
- Direct conversion of differential baseband I/Q (Baseband mode)
- Single-ended complex-IF operation (IF mode)
IF mode supports both internal or external hybrid
Programmable baseband I/Q common-mode voltage
Matched, 50 Ω impedance, single-ended RF input and output
Matched, 50 Ω impedance single-ended LO input
Low phase variation vs. gain control

Upconversion mode
- Sideband rejection and carrier feedthrough optimization
- Envelope detector for automatic, on-chip calibration
Downconversion mode
- Image rejection and I/Q imbalance optimization
- Baseband I/Q DC offset correction
- Receiver mixer power detector for receiver gain setting
LO chain features:
- Variable gain to accommodate various LO drive strength values
- 360° phase control shifter for LO synchronization
- Programmable LO harmonic reject filter
- I/Q phase correction
Fast TDD switching time via external pins
Programmable via a 3-wire or 4-wire SPI interface, compatible with ADMV4928 and ADMV4728 interface
