M1749B Performance mmWave Transceiver 22.7 – 49.2 GHz

Overview

The M1749B Performance mmWave Transceiver is designed to be used as the millimeter-wave interface between a wireless test system and a millimeter-wave Device Under Test. The M1749B upconverts the test system’s Tx output to the higher range of the DUT, and downconverts the received signal from the DUT to the lower range of the test system’s Rx input. The DUT-facing ports of the M1749B (RF Tx/Rx 1 and RF Tx/Rx 2) are half-duplex ports -- that is, either port can transmit or receive (although never both at once).

Remote Radio Head

Confidently test over the air at mmWave frequencies in the 24, 28, 39, 40 and 47 GHz bands using one M1749B remote radio head (RRH). Verify Tx and Rx performance of 5G RFFEs, base stations, chipsets and devices using stimulus and analysis provided by one of several Keysight platforms.

Multiple mmWave Bands

The M1749B is the only RRH supporting bi-directional testing at five mmWave frequency bands with one hardware set. Two RF ports support Tx and Rx verification.

Versatile 5G Solutions

Flexibly analyze mmWave 5G performance with or without signaling using the M1749BRRH with accompanying platforms. Improve time to market by finding and solving issues early in the product life cycle. Save valuable development and test time with consistent results from Keysight’s common measurement algorithms.

Performance Characteristics

Definitions

Specification (spec)

The warranted performance of a calibrated instrument that has been stored for a minimum of 2 hours within the operating temperature range and after a 30-minute warm up period. Specifications are valid from 20 to 30 °C unless otherwise noted.

Typical (typ)

Typical (typ) describes additional product performance information. It is performance beyond specifications that 95 percent of the units exhibit with a 95 percent confidence level at room temperature (approximately 23 °C). Typical performance does not include measurement uncertainty.

Nominal (nom)

The mean or average characteristic performance, or the value of an attribute that is determined by design. This data is not warranted and is measured at room temperature (approximately 23 °C).

Measured (meas)

An attribute measured during development for purposes of communicating the expected performance. This data is not warranted and is measured at room temperature (approximately 23 °C).

Conditions

The information in the following tables for TX and RX apply to the M1749B remote radio head in CW mode. All the modulation or de-modulation performances apply to their specific base instruments that supply the modulation signal along with other interfaces (IF, LO frequency and reference frequency).
