Cellular base stations Point-to-point radio links RF instrumentation GENERAL DESCRIPTION The ADL5350 is a high linearity, up-and-down converting The high input linearity of the ADL5350 makes the device an mixer capable of operating over a broad input frequency range. excellent mixer for communications systems that require high It is well suited for demanding cellular base station mixer designs blocker immunity, such as GSM 850 MHz/900 MHz and that require high sensitivity and effective blocker immunity. Based 800 MHz CDMA2000. At 2 GHz, a slightly greater supply on a GaAs pHEMT, single-ended mixer architecture, the ADL5350 current is required to obtain similar performance. provides excellent input linearity and a low noise figure without The single-ended broadband RF/IF port allows the device to be the need for a high power level LO drive. customized for a desired band of operation using simple external In 850 MHz/900 MHz receive applications, the ADL5350 filter networks. The LO-to-RF isolation is based on the LO provides a typical conversion loss of only 6.7 dB. The input IP3 rejection of the RF port filter network. Greater isolation can be is typically greater than 25 dBm, with an input compression achieved by using higher order filter networks, as described in point of 19 dBm. The integrated LO amplifier allows a low LO the Applications Information section. drive level, typically only 4 dBm for most applications. The ADL5350 is fabricated on a GaAs pHEMT, high performance IC process. The ADL5350 is available in a 2 mm × 3 mm, 8-lead LFCSP. It operates over a −40°C to +85°C temperature range. An evaluation board is also available. Rev. A Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
