TQM879008
1.5-2.7GHz ½ W Digital Variable Gain Amplifier
Notes:
1. For PCB Board Layout, see page 9 for more information.
2. All Components are of 0603 size unless stated otherwise.
3.
4. 0 Ω jumpers may be replaced with copper traces in the target application layout.
5. Different ground pins are used for SPI (digital) and analog supply voltages.
6. The primary RF microstrip characteristic line impedance is 50 Ω.
7. The single power supply is used to provide supply voltage to AMP1, AMP2 and AMP3.
