The MC13143 is a high compression linear mixer with single–ended RF
input, differential IF output and differential LO inputs which consumes as
little as 1.8 mW. A new circuit topology is used to achieve a high third order
intermodulation intercept point, high linearity and high 1.0 dB output
compression point while maintaining a linear 50 Ω input impedance. It is
designed for Up or Down conversion anywhere from dc to 2.4 GHz.

General
The MC13143 is a double–balanced Mixer. This device is
designated for use as the frontend section in analog and
digital FM systems such as Wireless Local Area Network
(LAN), Digital European Cordless Telephone (DECT), PHS,
PCS, GPS, Cellular, UHF and 800 MHz Special Mobile
Radio (SMR), UHF Family Radio Services and 902 to
928 MHz cordless telephones. It features a mixer linearity
control to preset or auto program the mixer dynamic range,
an enable function and a wideband IF so the IC may be
used either as a down converter or an up converter.
Current Regulation
Temperature compensating voltage independent current
regulators provide typical supply current at 1.0 mA with no
mixer linearity control current.
Mixer
The mixer is a unique and patented double–balanced four
quadrant multiplier biased class AB allowing for
programmable linearity control via an external current
source. An input third order intercept point of 20 dBm may be
achieved. All 3 ports of the mixer are designed to work up to
2.4 GHz. The mixer has a 50 Ω single–ended RF input and
open collector differential IF outputs (see Internal Circuit
Schematic for details). The linear gain of the mixer is
approximately –5.0 dB with a SSB noise figure of 12 dB.
Local Oscillator
The local oscillator has differential input configuration that
requires typically –10 dBm input from an external source to
achieve the optimal mixer gain.

CIRCUIT DESCRIPTION

MC13143
Evaluation PC Board
The evaluation PCB is very versatile and is intended to be
used across the entire useful frequency range of this device.
The PC board is laid out to accommodate all SMT
components on the circuit side (see Circuit Side Component
Placement View).
Component Selection
The evaluation PC board is designed to accommodate
specific components, while also being versatile enough to
use components from various manufacturers. The circuit side
placement view is illustrated for the components specified in
the application circuit. The Component Placement View
specifies particular components that were used to achieve
the results shown in the typical curves and tables.

Mixer Input
The mixer input impedance is broadband 50 Ω for
applications up to 2.4 GHz. It easily interfaces with a RF
ceramic filter as shown in the application schematic.
Mixer Linearity Control
The mixer linearity control circuit accepts approximately
0 to 2.3 mA control current. An Input Third Order Intercept
Point, IIP3 of 20 dBm may be achieved at 2.3 mA of control
current (approximately 7.0 mA of additional supply current).
Interface matching between the RF input, RF filter and the
mixer will be required. The interface matching networks
shown in the application circuit are designed for 50 Ω
interfaces.
Differential to single–ended circuit configuration is shown
in the test circuit. 6.0 dB of additional mixer gain can be
achieved by conjugately matching the output of the
MiniCircuits transformer to 50 Ω at the desired IF frequency.
With narrowband IF output matching the mixer performance
is 3.0 dB gain and 12 dB noise figure (see Narrowband 49
and 83 MHz IF Output Matching Options). Typical insertion
loss of the Toko ceramic filter is 3.0 dB. Thus, the overall gain
of the circuit is 0 dB with a 15 dB noise figure.

Local Oscillator Inputs
The differential LO inputs are internally biased at
VCC – 1.0 VBE; this is suitable for high voltage and high gain
operation.
For low voltage operation, the inputs are taken to VCC
through 51 Ω.
Input/Output Matching
It is desirable to use a RF ceramic or SAW filter before the
mixer to provide image frequency rejection. The filter is
selected based on cost, size and performance tradeoffs.
Typical RF filters have 3.0 to 5.0 dB insertion loss. The PC
board layout accommodates both ceramic and SAW RF
filters which are offered by various suppliers such as
Siemens, Toko and Murata.

NOTES: 926.5 MHz preselect dielectric filter is Toko part # 4DFA–926A10; the 4DFA (2 and 3 pole SMD type) filters are available
for applications in cellular and GSM, GPS, DECT, PHS, PCS and ISM bands at 902–928 MHz, 1.8–1.9 GHz at 2.4–2.5 GHz.
The PCB also accommodates a surface mount RF SAW filter in an eight or six pin ceramic package for the cellular base and
handset frequencies. Recommended manufacturers are Siemens and Murata.
The PCB may also be used without a preselector filter; AC coupled to the mixer as shown in the test circuit schematic.
All other external circuit components shown in the PCB layout above are the same as used in the test circuit schematic.
16:1 broadband impedance transformer is mini circuits part #TX16–R3T; it is in the leadless surface mount “TX” package. For a
more selective narrowband match, a lowpass filter may be used after the transformer. The PCB is designed to accommodate
lump inductors and capacitors in more selective narrowband matching of the mixer differential outputs to a single–ended output
at a given IF frequency.
.
The local oscillator may also be driven in a differential configuration using a coaxial transformer. Recommended sources are the
Toko Balun transformers type B4F, B5FL and B5F (SMD component).
