The Keysight E7770A common interface unit (CIU) provides a bidirectional intermediate frequency (IF) interface to the device under test (DUT) by up- or down-converting a sub-6 GHz uplink or downlink RF signal into a 6 to 12 GHz, or 7.7 to 14.5 GHz IF signal. This solution gives you the control, power, and local oscillator frequency input to the Keysight M1740A millimeter-wave (mmWave) transceiver for 5G remote radio heads (RRHs). As an up/down converter and RRH controller, the CIU supports the extension of the frequency coverage from sub-6 GHz to a high IF and mmWave bands.

The CIU is a key component of a wide range Keysight 5G solutions. These solutions provide the stimulus and analysis capabilities necessary to verify transceiver (Tx) and receiver (Rx) performance for 5G chipsets, devices, and base stations.

Quickly validate DUT performance over-the-air (OTA) with chambers designed for different test cases across the device workflow.

The M1749B is the only Remote Radio Head supporting bi-directional testing at five mmWave frequency bands with one hardware set. Two RF ports support Tx and Rx verification. Confidently test over the air at mmWave frequencies in the 24, 28, 39, 40 GHz, 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. M1749B delivers an additional +3 dBm power compared to M1749A.

The Keysight M1740A millimeter-wave (mmWave) transceiver for 5G is a versatile remote radio head covering multiple frequency bands. Two mmWave ports provide transmit and receive paths between the device under test and the test and measurement equipment in the solution. Use the M1740A mmWave transceiver with the Keysight E7770A common interface unit (CIU). Easily validate DUT performance over-the-air (OTA) test with chambers designed for different test cases across the device workflow.

Keysight’s multi-band M1740A remote radio head (RRH) enables users to confidently test over-the-air (OTA) in millimeter-wave (mmWave) frequency bands, including 24, 28, 39, and 40 GHz bands. The M1740A uniquely supports bi-directional testing across four mmWave frequency bands with a single hardware set.

Verify transmitter (Tx) and receiver (Rx) performance of 5G RFFEs, base stations, chipsets, and devices including UE power class 1 fixed wireless access (FWA) devices such as customer-premises equipment (CPE) using stimulus and analysis provided by one of several Keysight platforms.
