MAX2027 Evaluation Kit
General Description
Features
♦ Fully Assembled and Tested
♦ 50MHz to 400MHz Frequency Range
♦ Variable Gain: -8dB to +15dB
♦ Output IP3: 35dBm (All Gain Settings)
♦ Noise Figure: 4.7dB at Maximum Gain
The MAX2027 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX2027 high-linearity, digitally controlled,
variable-gain amplifier. The kit is fully assembled and
tested at the factory. Standard 50Ω SMA connectors
are included for the input and output to allow quick and
easy evaluation on the test bench.
This EV kit provides a list of equipment required to eval-
uate the device, a straightforward test procedure to ver-
ify functionality, a circuit schematic, a bill of materials
(BOM), and artwork for each layer of the PC board.
Contact MaximDirect sales at 888-629-4642 to check
pricing and availability of these kits.
♦ Digitally Controlled Gain with 1dB Resolution and
±0.05dB State-to-State Accuracy
