50Ω 0.05 to 3 GHz
31.5 dB, 0.5 dB Step, 6 Bit Serial Control
The Big Deal
• Integrated Amplifier and Digital Attenuator
• 19 dB Gain / 31.5 dB Gain Control
• Flat frequency response, ±0.7 dB (700-2100 MHz)
DVGA2-33+
CASE STYLE: DG1677
Product Overview
The DVGA2-33+ is a 50W RF Digital Variable Gain Amplifier that offers an attenuation of 31.5 dB in 0.5 dB
steps using a 6-bit serial interface attenuator and 19dB gain using a InGap HBT amplifier. Step attenuator
used in DVGA2-33+ is produced using a unique combination of CMOS process on silicon, offering the
performance of GaAs, with the advantages of conventional CMOS devices.
Key Features
Feature
31.5 dB attenuation in 0.5 dB step size
Flat frequency response, ±0.7 over
700-2100 MHz
Medium Gain, 19 dB
Advantages
Combining medium gain and a wide range of gain control makes the DVGA2-33+
an ideal building block for any RF chain where level setting control is required in a
small space.
No need for external components to flatten gain.
Incorporating multiple stages of amplification, the DVGA2-33+ provides medium
gain over a wideband reducing cost and PCB board space.
Good IP3, +30 dBm at 1.0 GHz
Use in receivers and transmitters giving the users advantage in instantenous spur
free dynamic range over wide bandwidths.
Output Power, +16.3 dBm at 1.0 GHz
The DVGA2-33+ maintains consistent output power capability over the full attenu-
ation range and operating temperature range making it ideal to be used in remote
applications such as LNB’s as the L Band driver stage.
Attenuation Step size, 0.5 dB, accuracy
0.1 to 0.5 dB typ. Total attenuation, 31.5 dB
Enables precise control of gain in 0.5 dB steps up to 31.5 dB.
MCLP Package
Low Inductance, repeatable transitions, excellent thermal pad.
PCB area reduction
The DVGA2-33+ combines multiple functions common to TX/RX architectures into
a single 5x5mm package
Flexibility in the application block diagram
The DVGA2-33+ provides access to the internal circuit through external jumper
(see simplified schematic) enables designers flexibility to incorporate a wide range
of additional circuits.
