1. DESCRIPTION

The ADL5350ACPZ-R7 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 ADL5350ACPZ-R7 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. The high input linearity of the ADL5350ACPZ-R7 makes the device an excellent mixer for communications systems that require high blocker immunity, such as GSM 850 MHz/900 MHz and 800 MHz CDMA2000. At 2 GHz, a slightly greater supply current is required to obtain similar performance. The single-ended broadband RF/IF port allows the device to be customized for a desired band of operation using simple external filter networks. The LO-to-RF isolation is based on the LO rejection of the RF port filter network. Greater isolation can be achieved by using higher order filter networks, as described in the Applications Information section. The ADL5350ACPZ-R7 is fabricated on a GaAs pHEMT, high performance IC process. The ADL5350ACPZ-R7 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.
