Function
Power Supply Decoupling. The nominal supply decoupling consists of
100 pF and 0.1 μF capacitors at each power supply pin (the VPS2 pins, Pin 18
to Pin 22, share a pair of decoupling capacitors because of their proximity). A
series inductor or small resistor can be placed between the capacitors for
additional decoupling.
Input Interface. The 1:1 balun transformer T1 converts a 50 Ω single-ended
input to the 50 Ω differential input. C5 and C6 are dc blocks.
Output Interface. The 1:1 balun transformer T2 converts the 50 Ω differential
output to 50 Ω single-ended output. C11 and C2 are dc blocks. L3 and
L4 provide dc biases for the output.
Enable Interface. The ADL5330 is enabled by applying a logic high voltage
to the ENBL pin by placing a jumper across SW1 to the O position. Remove
the jumper for disable. To exercise the enable function by applying an
external high or low voltage, use the pin labeled O on the SW1 header.
Alternate Input/Output Interface. The circuit side of the evaluation board
offers an alternate RF input and output interface. A lumped-element balun
can be built using L and C components instead of using the balun
transformer (see the Applications section). The components, M1 through
M9, are used for the input, and M10 through M18 are used for the output.
To use the alternate RF paths, disconnect the dc blocking capacitors
(Capacitor C5 and Capacitor C6 for the input and Capacitor C11 and
Capacitor C12 for the output). Place 100 pF dc blocking capacitors on
C15, C16, C17, and C18. Use the alternate set of SMA connectors,
INPUT2 and OUT2.
