General Description
The TQP569022 is a high-linearity, dual-channel down-
converter designed to provide a low cost solution for the
demanding functionality and performance goals of
current and next generation mobile infrastructure base
stations. It provides high dynamic range performance in
a low profile lead-free/RoHS-compliant surface-mount
6x6 mm leadless package.
This device is a fully integrated diversity mixer that
includes LO switch, two stage LO drivers, high-linearity
mixers, RF balun and IF amplifiers. The IF amplifiers
can be set to standard current or low current mode
through logic input pins. The TQP569022 also integrates
power down feature controlled by separate logic pin.
The TQP569022 provides 9 dB conversion gain, +25.5
dBm input IP3, +12 dBm input P1dB and a noise figure
of 10 dB over the 1700−2200 MHz frequency range for
diversity receiver applications. The TQP569022 is
optimized for low side LO applications but is also useful
in high side LO applications with less stringent linearity
requirements. The TQP569022 is footprint and pin
compatible with TriQuint’s 680 – 920 MHz TQP519021
mixer for low band applications.

1.7 – 2.2 GHz High IP3 Dual Channel Downconverter
Detailed Device Description
The TQP519021 is a high-linearity diversity dual-channel down-converter designed to meet the demanding performance, functionality,
and cost goals of current and next generation mobile infrastructure base stations. This device is fully integrated diversity mixer that
includes LO switch, two stage LO drivers, high-linearity mixers, RF balun and IF amplifiers. A single pole double throw (SPDT) high
isolation switch has been included to select between two different LO inputs for frequency hopping applications. IF amplifiers can be
set to standard current or low current mode through logic input pins. The TQP519021 also integrates power down feature controlled
by separate logic pin.
RF Port
The single-ended RF input ports of both the main and diversity channels are internally matched to 50Ω, requiring no external
matching components and DC-blocking capacitor. The RF input is internally transformed to a balanced signal using an internal, on-
chip unbalanced-to-balanced (balun) transformer. The RF balun can support an RF input frequency range of 600-1200 MHz.
LO Drivers and LO switch
The TQP519021 is optimized for a 600MHz to 1100MHz LO frequency range. The two stage LO drivers allow the LO input power to
be in the range of ±3 dBm. The LO section is optimized for low-side LO injection but also works for high-side LO applications with
slightly degraded linearity performance.
As an added feature, a single pole double throw (SPDT) switch has been included to select between two different LO inputs for
frequency hopping applications. The SPDT switch selects one of the two single-ended LO ports providing greater than 50 dB of LO1
to LO2 isolation. LO switching time is typically 100ns. The switch is controlled by a digital input (LOSEL), where logic-high selects
LO1 and logic-low selects LO2. LO1 and LO2 inputs are internally matched to 50Ω, requiring only 100pF DC-blocking capacitors.
Passive Double-Balanced Mixer
The TQP519021 consists of a passive, double balanced, high-performance mixer that provides a very low conversion loss and high
IIP3. Additionally, the balanced nature of the mixer provides for high channel to channel isolation.
IF Amplifiers
The TQP519021 has an IF frequency range of 70 – 280 MHz, where the low-end frequency depends on the frequency response of
the external IF components. The IF amplifiers follow the passive mixers in the signal path and can be operated outside of this range,
but with a slight degradation in performance. The outputs require a supply voltage connection using inductive chokes. The
differential output impedance of the IF amplifier is approximately 200 Ω. If operation in a 50 Ω system is desired, the output can be
transformed to 50 Ω by using a 4:1 transformer. One can use a differential IF amplifier on the mixer IF ports, but a DC block is
required on both IFD+/IFD- and IFM+/IFM- ports to keep external DC from entering the IF ports of the mixer. These differential ports
are ideal for providing better IIP2 performance.
Standard Current Mode and Low Current Mode
IF amplifiers can be set to standard current or low current mode through logic input pins. The IFD_CURR_SET and
IFM_CURR_SET pins (17 and 29, respectively) are used to reduce the IF amplifier bias current. On the evaluation board, this is
achieved by setting jumpers J10 and J12 as explained under Application Board section. The low current mode degrades IIP3
performance. The total current draw with low current mode is about 100mA lower than standard current mode. The
IFD_CURR_SET and IFM_CURR_SET pins can be left either NC or GND for the applications not using low current mode.
Shutdown Mode
The TQP519021 has additional integrated feature of power shut down for IF amplifiers and LO amplifier. The IFD_SD and IFM_SD
pins (18 and 28, respectively) are used for IF amplifier shut down. The LOD_SD and LOM_SD pins (22 and 24, respectively) are
used for LO amplifier shut down. On the evaluation board, this is achieved by setting jumpers J11, J13, J16 and J9 as explained
under Application Board section. The total current draw during shut down mode is 3.5mA. The IFD_SD and IFM_SD pins can be left
either NC or GND for the applications not using shutdown mode.
