). See Figure 1.
The 5 MSBs of the 10-bit word program attenuator A,
and the 5 LSBs of the 10-bit word program attenuator
B. Each bit sets the attenuators to a corresponding
attenuation level. For example, logic-low 0 for bit 5 and
bit 0 of attenuator A and B, respectively, sets both
attenuators at 1dB. 00000 configures both attenuators
for maximum attenuation and 11111 sets for minimum
attenuation. See Table 1 for programming details.
External Bias
Bias currents for the two-stage amplifier and the loop-
back mixer are set and optimized with external resistors.
Resistor R1 (pin 31) sets the bias current for the input
amplifier, R2 (pin 20) sets the bias current for the output
amplifier, and R3 (pin 40) sets the bias for the loopback
mixer. The external biasing resistor values can be
increased for reduced current operation at the expense
of performance. Contact the factory for details.
Board Layout
The pin configuration of the MAX2059 has been opti-
mized to facilitate a very compact physical layout of the
device and its associated discrete components.
The exposed paddle (EP) of the MAX2059’s thin QFN-
EP package provides a low thermal-resistance path to
the die. It is important that the PC board on which the
MAX2059 is mounted be designed to conduct heat
from the EP. In addition, provide the EP with a low-
inductance path to electrical ground. The EP
MUST
be
soldered to a ground plane on the PC board, either
directly or through an array of plated via holes.
