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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Handling Precautions
Although protection circuitry has been designed into this device, proper precautions should be taken to avoid
exposure to electrostatic discharge (ESD) during handling and mounting. Lucent Technologies Microelectronics
Group employs a human-body model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing
and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used to define
the model. No industry-wide standard has been adopted for CDM. However, a standard HBM (resistance =
1500
, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM
ESD threshold presented here was obtained by using these circuit parameters:

Operating Ranges
This table lists the ranges of external conditions in which the W3013 provides general functionality that may be
useful in specific applications without risk of permanent damage. However, performance is not guaranteed over
the full range of all possible conditions. The conditions for guaranteed performance are described in the
Electrical Characteristics table.
