LTC5548IUDB#TRMPBF - RF Mixer by Analog Devices Inc.

The LTC5548IUDB#TRMPBF is a high-performance, passive double-balanced mixer from Analog Devices Inc., designed to address the demanding requirements of wireless infrastructure and RF applications. This RF mixer is a part of the extensive portfolio of RF integrated circuits that Analog Devices offers, known for their reliability and cutting-edge performance.

This device operates within the frequency range of 2 GHz to 14 GHz at the RF and LO ports, providing a versatile solution for various frequency conversion applications. The IF port supports frequencies from DC to 6 GHz, enabling a broad range of intermediate frequencies to be utilized. The LTC5548IUDB#TRMPBF boasts an impressive conversion gain of 2.4 dB, which helps to maintain signal integrity through the mixing process.

The mixer's low LO to RF leakage of -25 dBm ensures minimal interference and cross-talk between the local oscillator and the RF signal, which is critical for maintaining a clean and undistorted output. Additionally, the device exhibits an excellent 2x2 and 3x3 spurious suppression, further enhancing the mixer's ability to deliver a clear signal.

With an IP3 (Input Third-Order Intercept Point) of 24.4 dBm, the LTC5548IUDB#TRMPBF can handle high input power levels without significant distortion, making it suitable for high-dynamic-range receivers. The mixer's integrated balun simplifies the board layout and reduces external component requirements, which can save valuable board space and reduce overall system complexity.

This product is available in a compact 12-lead, 3mm x 2mm DFN package, which is ideal for space-constrained applications. The LTC5548IUDB#TRMPBF is also designed to operate over a wide temperature range of -40°C to 105°C, ensuring consistent performance across various environmental conditions.

Analog Devices Inc. has optimized the LTC5548IUDB#TRMPBF for low power consumption, drawing a typical supply current of 132 mA. This makes it a suitable choice for portable and battery-powered equipment where power efficiency is paramount. With its robust feature set and high level of integration, the LTC5548IUDB#TRMPBF is an excellent choice for designers looking to implement high-frequency mixing with minimal effort and maximum performance.
