Digital Controlled Variable Gain Amplifier
50Ω 0.45 to 2.4 GHz
31.5 dB, 0.5 dB Step, 6 Bit Parallel Control
The Big Deal
• Integrated Amplifier and Digital Attenuator
• 30 dB Gain / 31.5 dB Gain Control
• High Output IP3, 34-37 dBm
DVGA1-242PP+
CASE STYLE: DG1677
Product Overview
The DVGA1-242PP+ is a 50Ω RF Digital Variable Gain Amplifier that offers an attenuation of 31.5 dB in
0.5 dB steps using a 6-bit parallel interface attenuator and 30dB gain using a E-PHEMT amplifier. Step
attenuator used in DVGA1-242PP+ is produced using a unique combination of CMOS process on silicon,
offering the performance of GaAs, with the advantages of conventional CMOS devices.

Advantages
Combining high gain and a wide range of gain control makes the DVGA1-242PP+
an ideal building block for any RF chain where level setting control is required in
fast speed of parallel control interface.
Incorporating multiple stages of amplification, the DVGA1-242PP+ provides high
gain reducing cost and PCB board space
Combining Low Noise and High IP3 makes this MMIC amplifier ideal for Low Noise
Receiver Front End (RFE) giving the user advantages at both ends of the dynamic
range: sensitivity & two-tone IM dynamic range.
The DVGA1-242PP+ maintains consistent output power capability over the full
operating temperature range making it ideal to be used in remote applications such
as LNB’s as the L Band driver stage.
Low Inductance, repeatable transitions, excellent thermal pad.
Ruggedized design operates up to input powers often seen at Receiver inputs.
Enables precise control of gain in 0.5 dB steps up to 31.5 dB.
Customer access is provided between the digital attenuator and the RF amplifier to
allow the user to integrate external circuit elements if desired.

Notes:
1. All RF input and output ports shall be AC coupled with external blocking capacitor.
2. Latch Enable (LE) has an internal 100KW pull-up resistor to VD1
3. Place a 10KW resistor in series, as close to pin as possible to avoid freq. resonance (see layout drawing PL-382).
4. Place a 10KW resistor to ground.
5. The exposed solder pad on the bottom of the package (See Pin Configuration) must be grounded for proper device operation
6. See application and characterization test circuit and layout drawing PL-382.
