downconverting mixer applications that require very high
dynamic range. The LTC5551 covers the 300MHz to
3.5GHz RF Frequency range with LO frequency range
of 200MHz to 3.5GHz. The LTC5551 provides very high
IIP3 and P1dB with low power consumption. A typical
application is a basestation receiver covering 700MHz to
2.7GHz frequency range. The RF input can be matched for a
wide range of frequencies and the IF is usable up to 1GHz. n A low power mode is activated by pulling the ISEL pin high,
reducing the power consumption by about 1/3, however, …
