The ADL5205 is a digitally controlled, wide bandwidth, variable gain dual amplifier (DGA) that provides precise gain control, high output third-order intercept (OIP3) and a near constant noise figure for the first 12 dB of attenuation. The excellent OIP3 performance of 48.5 dBm (at 200 MHz, 5 V, high performance mode, and maximum gain) makes the ADL5205 an excellent gain control device for a variety of receiver applications.

For wide input dynamic range applications, the ADL5205 provides a broad 35 dB gain range with a 1 dB step size. The gain is adjustable through multiple gain control and interface options: parallel, SPI, or gain step up/down control.

The two channels of the ADL5205 can be powered up independently by applying the appropriate logic level to the PWUPA and PWUPB pins. The quiescent current of the ADL5205 is typically 175 mA for high performance mode and 135 mA for low power mode. When disabled, the ADL5205 consumes only 14 mA and offers excellent input to output isolation. The gain setting is preserved when the device is disabled.

Fabricated on the Analog Devices, Inc., high speed, silicon germanium (SiGe) complementary BiCMOS process, the ADL5205 provides precise gain adjustment capabilities with good distortion performance. The ADL5205 amplifier comes in a compact, thermally enhanced, 6 mm × 6 mm, 40-lead LFCSP package and operates over the temperature range of −40°C to +85°C.

Note that throughout this data sheet, multifunction pins, such as CSA/A3, are referred to by the entire pin name or by a single function of the pin, for example, CSA, when only that function is relevant.

Product Detail

The ADL5205-EVALZ evaluation board provides interfaces to the ADL5205 Dual DGA through serial and the parallel interface ports, as well as through the USB port on a Microsoft® Windows® PC via the system demonstration platform (SDP) interface board. Additionally, toggle switches allow the manually control of all the digital functions for the Dual DGA.

A 3.3 V low dropout (LDO) voltage regulator supplies the logic circuits when the device is running on a 5 V supply. On-board baluns convert single-ended input signals to differential form for input to the device and convert the differential output signals of the device to single-ended form for output.

The ADL5205-EVALZ evaluation board is built on a 4-layer 370HR (FR4) Printed Circuit Board.
