HMC1190LP6GE
v01.1112
BROADBAND HIGH IP3 DUAL CHANNEL DOWNCONVERTER
w/ Fractional-N PLL & VCO, 0.7 - 3.5 GHz
Application Information
The HMC1190LP6GE is a broadband dual channel, high dynamic range, high gain, low noise, high-linearity down
converting mixer with integrated Fractional-N Integer-N PLL and VCO, designed to cover RF frequencies from 700
MHz to 3.5 GHz. The HMC1190LP6GE`s low noise and high linearity performance makes it suitable for a wide range
of transmission standards, including TDD, FDD, LTE, WiMAX, CDMA,GSM, MC-GSM, W-CDMA, UMTS, TD-SCDMA
applications.
The HMC1190LP6GE offers an easy-to-use and complete frequency conversion solution for diversity and MIMO
receiver applications in a highly compact 6x6 mm plastic QFN package. The HMC1190LP6GE greatly simplifies the
design of diversity and MIMO receiver applications by increasing the integration level and reducing the number of
required circuit elements thereby reducing cost, area, and power consumption.
Principle of Operation
HMC1190LP6GE’s single-ended RF inputs are converted into differential through the on-chip integrated baluns. The
single-ended RF inputs are internally broadband matched to 50 Ω and require only standard DC-blocking capacitors.
HMC1190LP6GE’s RF inputs can be externally matched for narrow band application frequencies with a simple
matching network including a series inductor, and a shunt capacitor to further improve the performance. Please refer
to the application circuit for narrow band RF input matching for the detailed information.
The HMC1190LP6GE’s IF amplifiers are designed for differential 200 Ω output load impedance. A few external
components are required at these IF outputs for the broadband frequency response as recommended in the application
circuit.
Refer to the IF output interface section for detailed information.
The HMC1190LP6GE requires 5V, 3.3V and 3V supply voltages and external bias voltages. Bias voltages generate
reference currents for the IF and LO amplifiers. 3.3V supply voltage and the external bias voltages can be generated
from 5V supply voltage to operate with a single supply. Please refer to the single supply operation section for more
information.
The reference currents to the IF and LO amplifiers can be disabled through SPI interface. See `Enabling / Disabling
Mixer Features` section for details.
Supply Number Reduction
The LOVDD, VCS1, VCS2, LOBIAS1, LOBIAS2, VGATE1 and VGATE2 pins of HMC1190LP6GE requires different
supply voltages.
Except LOVDD, other pin voltages i.e. VGATE1, VGATE2, LOBIAS1, LOBIAS2, VCS1, VCS2 voltages are already
generated from 5.5V supply voltage on evaluation board (see application circuit). These bias voltages can be optimized
by external resistors (VCS1, VCS2, LOBIAS1, LOBIAS2, VGATE1, and VGATE2). The resistor values of VCS1, VCS2
on evaluation board are 590 Ohms. LOBIAS1 and LOBIAS2 series resistor values are 270 Ohms. Refer to the VCS
Interface and LOBIAS Interface section for more information.
On the evaluation board, VGATE1, VGATE2 pin voltages are 5V; however VGATE1, VGATE2 pin voltages can be
tuned between 4.7V and 5V for optimization of Input IP3 and conversion gain performances. After VGATE1,VGATE2
pin voltages are optimized, these pin voltages can be generated from 5V supply by changing the values of series
resistors, R14 and R15. Refer to the VGATE interface section for more information.
The 3 V supply voltage for the LO amplifiers can be generated from 5 V or 3.3 V supply voltages by adding a series
resistor (R_LOVDD) between LOVDD pin and supply voltage in the configuration shown in Figure 1.
