The ADRF6573 is a high performance, digitally controlled, dual variable gain amplifier (VGA) operating from 100 MHz to 4000 MHz. Each channel includes a 6-bit digital step attenuator (DSA) with a 31.5 dB gain control range, 0.5 dB steps, and ±0.25 dB gain accuracy. The attenuation of the DSA is controlled using a serial peripheral interface (SPI). The SPI is a serial in, parallel out shift register buffered by a transparent latch. It is controlled by three CMOS-compatible signals: data, clock, and latch enable. The amplifier in each channel is a broadband linear amplifier that operates up to 4000 MHz.

The device is internally matched to 50 Ω at the input and output. Only input/output ac coupling capacitors and power supply decoupling capacitors are required for operation.

The ADRF6573 consumes 85 mA per channel and operates from a single supply ranging from 4.75 V to 5.25 V. It is fully specified for operation from −40°C to +85°C.

The ADRF6573 is packaged in a 32-terminal, 7 mm × 7 mm × 1.0 mm, land grid array (LGA) package.

Product Detail

ADRF6573-EVALZ is a fully populated, 4-layer, Rogers 3003-based evaluation board. For normal operation, it requires a 5 V/300 mA power supply. The ADRF6573 in the evaluation board can be programmed through a USB adaptor board from the USB port of a PC running Windows XP , Vista, and Window 7 with Microsoft .NET Framework 3.5 installed. The required control software can be downloaded from www.analog.com. The DSA and the amplifiers in ADRF6573 can be individually biased to the clip leads labeled VDD, VCC1, VCC2 and GND as well as connected to the VDD power plane using R1, R5 and R6.
