Радиочастотные средства разработки ADL5243-EVALZ

Оценочный модуль , ADL5243 РЧ/ПЧ усилитель с регулируемым усилением и цифровым управлением

The ADL5243-EVALZ is an evaluation platform for ADL5243 VGA. The ADL5243 is a high performance, digitally controlled variable gain amplifier operating from 100MHz to 4000MHz. The VGA integrates two high performance amplifiers and a digital step attenuator (DSA). Amplifier 1 (AMP1) is an internally matched gain block amplifier with 20dB gain and Amplifier 2 (AMP2) is a broadband ¼W driver amplifier that requires very few external tuning components. The DSA is 6bit with a 31.5dB gain control range, 0.5dB steps and ±0.25dB step accuracy. The attenuation of the DSA can be controlled using a serial or parallel interface. For normal operation ADL5243-EVALZ evaluation board requires a 5V/200mA power supply. The evaluation board can be programmed through the USB port of a PC running Windows XP or Vista with Microsoft .NET Framework 3.5 installed.

• Digitally controlled VGA with serial and parallel interfaces
• Low quiescent current of 175mA
• Single supply operation from 4.75V to 5.25V
