3 Description
The LMX8410L is a high-performance wideband (RF
frequency input from 4 to 10 GHz) I/Q demodulator
with an integrated LO and IF amplifier. With IIP3 of
28 dBm and NF of 15 dB (both at 5GHz), it provides
excellent dynamic range for high performance
applications. The device offers large complex
bandwidth of 2.7 GHz for high data-rate applications.
The LMX8410L offers an automatic DC offset
correction algorithm that reduces the offset to less
than ±2 mV. Fine control of gain and phase of I and
Q channels is enabled using SPI interface to achieve
high image rejection.
The LMX8410L has a high level of integration
providing high performance while saving board space
and complexity. It integrates a wideband RF input
balun, eliminating the need for external baluns. It
integrates a high-performance PLL and VCO,
eliminating the need for external LO and LO driver.
The device also integrates an IF amplifier and several
low noise LDOs, further simplifying the board.
The LMX8410L integrates a very low-noise
synthesizer, with a PLL FOM of –236 dBc/Hz,
providing up to 56.5-dBc DSB integrated noise at
5 GHz carrier. The LO allows for phase
synchronization across multiple devices. The high-
performance synthesizer output can be brought out to
drive another stage or a data converter. The
integrated LO can be bypassed for applications that
share a common external LO.
