The user can tailor the biasing of the LT5521 to meet
individual system requirements. It is recommended to
choose a source resistance as large as possible to mini-
mize sensitivity to power supply variation.
Output Interface
A DC connection to V
CC
must be provided on the PCB to the
output pins. These pins will draw approximately 20mA
each from the power supply. On-chip, there is a nominal
300
differential resistance between the output pins.
Figure 9 shows a typical matching circuit using an external
balun to provide differential to single-ended conversion.
LO suppression and 2xLO suppression are influenced by
the symmetry of the external output matching circuitry.
PCB design must maintain the trace layout symmetry of
the output pins as much as possible to minimize these
signals.
The M/A-COM ETC1.6-4-2-3 4:1 transformer (T2, Fig-
ure9) is suitable for applications with output frequencies
between 500MHz and 2700MHz. Output matching at vari-
ous frequencies is achieved by adding inductors in series
with the output (L1, L2) and DC blocking capacitor C3, as
shown in Figure 9. Table 6 specifies center frequency and
bandwidth of the output match for different matching
configurations. Figure 10 shows the typical output return
loss vs frequency for 1GHz and 2GHz applications. Capaci-
tor C12 provides a solid AC ground at the RF output
frequency.
