Description
The W3013 is a monolithic integrated circuit that
provides indirect, quadrature modulation of an RF
carrier by I & Q baseband inputs. The function
performed by the W3013 is particularly suited for
handheld digital cellular and digital cordless
telephones that operate between 800 MHz and
2.2 GHz.
The circuit block diagram is shown below. From a
single local-oscillator input (LO1), the phase
shifter produces two LO signals with 90° phase
separation and equal amplitude. The LO signals
are fed to the in-phase (I) and quadrature (Q)
double-balanced mixers. The resulting signals are
summed and fed into an RF mixer where the
frequency can be translated to over 2 GHz.
Outputs between the summer and RF mixer are
available for external filtering. Finally, the signal is
amplified to provide a single-ended output.
The ENB/APC input with a logic low allows the
device to be put into a powerdown mode. Above
the logic low threshold, the device enters a power
control mode that provides a range of desired
output power levels.
