ADL5350

Data Sheet FEATURES Broadband radio frequency (RF), intermediate frequency (IF), and local oscillator (LO) ports Conversion loss: 6.8 dB Noise figure: 6.5 dB High input IP3: 25 dBm High input P1dB: 19 dBm Low LO drive level Single-ended design: no need for baluns Single-supply operation: 3 V at 19 mA Miniature, 2 mm × 3 mm, 8-lead LFCSP RoHS compliant APPLICATIONS Cellular base stations Point-to-point radio links RF instrumentation GENERAL DESCRIPTION The ADL5350 is a high linearity, up-and-down converting mixer capable of operating over a broad input frequency range. It is well suited for demanding cellular base station mixer designs that require high sensitivity and effective blocker immunity. Based on a GaAs pHEMT, single-ended mixer architecture, the ADL5350 provides excellent input linearity and a low noise figure without the need for a high power level LO drive. In 850 MHz/900 MHz receive applications, the ADL5350 provides a typical conversion loss of only 6.7 dB. The input IP3 is typically greater than 25 dBm, with an input compression point of 19 dBm. The integrated LO amplifier allows a low LO drive level, typically only 4 dBm for most applications.
