ADI LTC5548IUDB High IIP3 Microwave Double-Balanced Mixer (2 GHz-14 GHz RF, DC-6 GHz IF, QFN-12 Package, for Microwave Communication Applications)

Large Quantities, Price Negotiable!

The LTC5548IUDB is a high-performance microwave double-balanced passive mixer from Analog Devices (ADI) designed for upconversion and downconversion applications, covering a wide frequency band from 2 GHz to 14 GHz (C-, X-, and Ku-bands). Combining high linearity, low noise, and low power consumption, it is ideal for microwave communication systems requiring high dynamic range.

Key Features:
1 Frequency Range:
1.1 RF Port: 2 GHz to 14 GHz
1.2 IF Port: DC to 6 GHz (Wideband Differential Port)
1.3 LO Frequency: 1 GHz to 12 GHz (Integrated LO Buffer, Requires Only 0 dBm Drive)
2 High Linearity:
2.1 Third-Order Intercept Point (IIP3): +24.4 dBm at 5.8 GHz, +21.4 dBm at 9 GHz
2.2 Input P1dB (1 dB Compression Point): +15.2 dBm at 5.8 GHz
3 Low Loss and Noise:
3.1 Conversion Loss: 7.1 dB (Typical)
3.2 Noise Figure (NF): 9.6 dB
4 Integrated Functionality:
4.1 Built-in LO Frequency Doubler, Bypassable via CMOS-Compatible Digital Pin
4.2 Low LO-RF Leakage (<-30dBm) reduces signal interference.
4.3 Fast on/off functionality for TDD (time division duplex) systems.
5 Electrical Characteristics:
5.1 Operating Voltage: 3.3V, Current 120mA to 136mA (Low Power Design)
