The LT5517EUF from Linear Technology is a state-of-the-art quadrature demodulator that is designed to provide exceptional performance in a wide range of wireless communication systems. This versatile component is ideal for applications such as base station receivers, diversity receivers, and broadband wireless systems, thanks to its high linearity and low noise characteristics.

The LT5517EUF operates at a frequency range of 40MHz to 900MHz, making it suitable for a variety of communication bands including FM, VHF, UHF, and L-band frequencies. Its input IP3 (third-order intercept point) is typically 25.5dBm at 190MHz, ensuring robust performance even in the presence of strong interfering signals.

This demodulator features an integrated LO buffer, which simplifies the design by eliminating the need for an external local oscillator amplifier. Additionally, the LT5517EUF boasts an integrated RF balun that allows for single-ended RF inputs, further simplifying the design and reducing component count.

With a conversion gain of 1.6dB, the LT5517EUF provides a balanced output that can directly interface with most analog-to-digital converters (ADCs) or baseband amplifiers. Its noise figure is a low 10.7dB, contributing to the overall sensitivity of the receiver system.

The device is packaged in a compact 16-lead QFN package with an exposed pad for excellent thermal performance. This package is only 4mm x 4mm, making it an ideal choice for space-constrained applications. The operating temperature range of -40°C to 85°C ensures reliable performance across a wide range of environmental conditions.

Linear Technology's LT5517EUF quadrature demodulator is a high-quality solution for designers looking to enhance the performance of their communication systems with a reliable, high-performance component.
