0.6-1.0GHz ¼W Digital Variable Gain Amplifier
Detailed Device Description
AMP1
AMP1 is a wide band low noise amplifier gain block in DVGA module. The amplifier provides 14.5 dB gain, 2.0 dB noise
figure, +40.6 dBm OIP3 at 0.9 GHz while only drawing 85 mA current. External DC blocks and biasing is not required.
AMP1 is DC blocked internally and is connected internally to two bypass capacitors (100 pF, 0.1 uF) followed by 68 nH
inductor inside the module as shown in the figure below.
DSA (Digital Step Attenuator)
DVGA has a serial digital step attenuator that is controlled with 6-bit serial periphery interface (SPI
size with 31.5 dB attenuation range. This 50-ohm RF DSA maintains high attenuation accuracy over frequency and
temperature. “000000” represents maximum attenuation state. External bypass capacitors are needed to compensate the
inductance effect associated with long transmission lines on the evaluation board.
AMP2
AMP2 is high linearity ¼-W amplifier in DVGA module. The amplifier provides 18.4 dB gain, +24.3 dBm P1dB, +39.5 dBm
OIP3 at 0.9 GHz while only drawing 87 mA current. The amplifier is tuned over 0.6 – 1.0 GHz bandwidth using internal
matching components. AMP2 is DC blocked internally and is connected internally to two bypass capacitors (100 pF, 0.1 uF)
followed by a 47 nH inductor inside the module as shown in the figure below. External DC blocks and biasing is not required.
