Function
Baseband Q-axis positive input
Supply voltage
Ground
Positive local oscillator input, nominal DC voltage is 2.0 V internally biased; input should be AC-coupled
Negartive local oscillator input, nominal DC voltage is 2.0 V internally biased; input should be AC-coupled
Ground
Shutdown control
Baseband I-axis positive input
Baseband I-axis negative input
Supply voltage
Ground
Negative RF output; nominal DC voltage is 2.4 Vinternally biased; input should be AC-coupled
Positive RF output; nominal DC voltage is 2.4 V internally biased; input should be AC-coupled
Ground
Supply voltage
Baseband Q-axis negative input
Device ground and heat sink, requires good thermal path; RF reference plane
Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
