Note 1:
Devices are production tested at T
A
= +25
°
C. Minimum and maximum values are guaranteed by design and characteriza-
tion over temperature and supply voltages to ±6 sigma.
Minimum DC voltage through a 10k
resistor that sets the MAX2654/MAX2655 to operate in normal mode and MAX2656 in
low-gain mode.
Maximum DC voltage through a 10k
resistor that sets the MAX2654/MAX2655 to operate in shutdown mode and
MAX2656 in high-gain mode.
DC current required when V
RFOUT
is connected to V
CC
through a 10k
resistor.
DC current required when V
RFOUT
is connected to GND through a 10k
resistor.
Guaranteed by design and characterization to ±3 sigma.
The part has been characterized at the specified frequency range. Operation outside of this range is possible, but not
guaranteed.
Production tested at T
A
= +25
°
C.
Measured with two input tones, f
1
= 1570MHz, f
2
= 1580MHz, both at -30dBm per tone.
Note 10:
Excludes PC board losses of 0.2dB for MAX2654/MAX2655 and 0.25dB for MAX2656.
Note 11:
High-gain mode is set up by connecting RFOUT to GND through a 12k
resistor.
Note 12:
Low-gain mode is set up by connecting RFOUT to V
CC
through a 12k
resistor.
Note 13:
Measured with two input tones, f
