Printed Circuit Board Material: .014” FR-4, 4 layers, .062” total thickness CV211-1: The application circuit can be broken up into three main functions as denoted in the colored dotted areas above: RF/IF diplexing (blue), IF amplifier matching (green), and dc biasing (purple). There are various placeholders for chip components in the circuit schematic so that a common PCB can be used for all WJ dual-branch converters. Further details are given in the Application Note located on the website titled “CV2xx Series - PWB Design Guidelines”. External Diplexer: This is only used with the cellular-band CV products. The mixer performs the diplexing internally for the CV211-1; therefore the components shown in the diplexer section should be not be loaded except for L3, L10, L7, and L11, which should contain a 0 Ω jumper. IF Amplifier Matching: The IF amplifier requires matching elements to optimize the performance of the amplifier to the desired IF center frequency. Since IF bandwidths are typically on the order of 5 to 10%, a simple two element matching network, in the form of either a high-pass or low-pass filter structure, is sufficient to match the MMIC IF amplifier over these narrow bandwidths. Proper component values for other IF center frequencies can be provided by emailing to [email protected]. DC biasing: DC bias must be provided for the LO and IF amplifiers in the converter. R1 sets the operating current for the last stage of the LO amplifier and is chosen to optimize the mixer LO drive level. Proper RF chokes and bypass capacitors are chosen for proper amplifier biasing at the intended frequency of operation. The “+5 V” dc bias should be supplied directly from a voltage regulator.
