The latest RF/IF integrated circuit (IC) AD8344 from Analog Devices (ADI) is an active receive mixer that is ideal for demanding signal processing applications in wireless infrastructure design. In addition to providing design engineers with design flexibility in frequency allocation and IF selection, the AD8344 is also the product with the smallest package and lowest power consumption performance indicators in the current RF IC market. Unlike traditional passive mixers that require many external components, the AD8344 active mixer integrates an on-chip local oscillator (LO) driver and provides conversion gain, thus minimizing the components required for external gain circuits. Among its main features, the AD8344 provides design engineers with a high degree of design flexibility in frequency allocation and IF selection. To this end, the device has 50Ω broadband inputs for both RF and LO ports. Its input frequency range is 400 MHz to 1.2 GHz, the LO frequency range is 400 MHz to 1.6 GHz, and the IF frequency range is 70 MHz to 400 MHz. The AD8344 is manufactured using Analog Devices' advanced silicon-germanium (SiGe) complementary bipolar IC process. At 900 MHz, the AD8344 features high input linearity of +24 dBm input third-order node (IIP3), +3 dB conversion gain, and 11.5 dB noise figure. At 450 MHz, the AD8344 features high input linearity of +15-dBm IIP3, +10 dB conversion gain, and 8.5 dB noise figure. The low-power AD8344 operates from a single +5 V supply and requires a –10 dBm to +4 dBm LO drive. The device is the smallest active mixer on the market today, in a small 3 mm × 3 mm LFCSP package. The device is ideal for cellular GSM, CDMA, and dedicated mobile access equipment, such as terrestrial trunked radio (TETRA).
