Linear Technology DC426B Quick Start Quide

DC426B DEMO BOARD QUICK START GUIDE Description: The DC426B demo circuit board is intended to demonstrate the capabilities of the LT5511 high signal level upconverting mixer IC for 1900MHz infrastructure applications. The LT5511 mixer IC is designed to meet the high linearity requirements of cable TV infrastructure downstream transmitters and wire ...

LT5511 Upconverting Mixer Single-Tone Measurements for 1900MHz Band. 1. Connect all test equipment as shown in Figure 2. 2. Set the Power Supply output voltage to 5V, and set the current limit to 100mA. 3. Set the dipswitch SW1 (Enable) to 1. Mixer is in ENABLE mode. 4. Set the Signal Generator #1 to provide a 1950MHz, -10dBm, CW signal to the demo ...

LT5511 Upconverting Mixer Two-Tone Measurements for 1900MHz Band. 1. Connect all test equipment as shown in Figure 3. Note: 1). A high quality combiner that provides 50-ohm termination on all ports and has good port-to-port isolation should be used. 2). The two 3dB attenuators on the inputs of the combiner are used to further improve source isolatio ...
