ADL5350是一款高线性度、上/下变频混频器,能够在较宽的输入频率范围内工作,非常适合要求高灵敏度和高效抗扰度的蜂窝基站混频器设计。这款器件基于GaAs pHEMT、单端混频器架构,能提供出色的输入线性度和低噪声系数,而无需高功耗本机振荡器(LO)驱动。
在850 MHz/900 MHz接收应用中,ADL5350的典型变频损耗仅为6.8 dB。集成的LO放大器只需一个低LO驱动电平,对于大多数应用,其典型值仅为4 dBm。输入IP3典型值大于25 dBm,输入压缩点为19 dBm。该器件具有高输入线性度,因而是适合GSM 850/900和800 MHz CDMA2000等要求高抗扰度通信系统的出色混频器。在2 GHz时,需要一个略微较高的电源电流才能获得类似的性能。借助单端宽带RF/IF端口,该器件能够利用简单的外部滤波器网络,针对所需工作频带进行定制。LO至RF隔离基于RF端口滤波器网络的LO抑制。采用更高阶滤波器网络可以实现更大的隔离,详情参见本数据手册的应用信息部分。ADL5350采用GaAs pHEMT、高性能IC工艺制造,提供3 mm x 2 mm、8引脚LFCSP封装,工作温度范围为−40°C至+85°C,同时提供评估板。
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 low noise figure without the need for a high power level local oscillator (LO) drive.
In 850 MHz/900 MHz receive applications, the ADL5350 provides a typical conversion loss of only 6.8 dB. The integrated LO amplifier allows a low LO drive level, typically only 4 dBm for most applications. The input IP3 is typically greater than 25 dBm, with an input compression point of 19 dBm. The high input linearity of the ADL5350 makes the device an excellent mixer for communications systems that require high blocker immunity, such as GSM 850/900 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 may be achieved by using higher order filter networks, as described in the Applications Information section of this data sheet.The ADL5350 is fabricated on a GaAs pHEMT, high performance IC process. The ADL5350 is available in a 3 mm x 2 mm 8-lead LFCSP. It operates over a −40°C to +85°C temperature range. An evaluation board is also available.
