SVG-2066 / SVG-2066Z
Product Description
Sirenza Microdevices’ SVG-2066 is an IC based 6-bit digi-
tal 31.5dB range attenuator cascaded with a linear class A
amplifier in a low-cost surface-mountable 6x6 QFN plastic
package. This product is specifically designed as a high lin-
earity variable gain amplifier for infrastructure equipment
that can be used in either the RF transmit or RF receive
path. It features both parallel or serial programmability, pro-
grammable power up states, latchable parallel control, 3V
or 5V combatible logic and robust Class 1B ESD. The SVG-
2066 features configurable pin I/O’s for optimizing the part
over application specific bands.
