MAX9987/MAX9988 Evaluation Kits
General Description
Features
The MAX9987/MAX9988 evaluation kits (EV kits) simpli-
fy the evaluation of the MAX9987/MAX9988 LO
buffers/splitters. They are fully assembled and tested at
the factory. Standard 50Ω SMA connectors are includ-
ed on the EV kits for the input and all three outputs to
allow quick and easy evaluation on the test bench.
ꢀ Fully Assembled and Tested
ꢀ Two-Way Power Splitting
ꢀ +14dBm to +20dBm Output Power
ꢀ
1dB Output Power ꢀariation
ꢀ Isolated PLL Output (+3dBm)
This document provides a list of equipment required to
evaluate the device, a straight-forward test procedure
to verify functionality, a circuit schematic for the EV kits,
a bill of materials (BOM) for the EV kits, and artwork for
each layer of the PC boards.
ꢀ Low Output Noise
