MOTOROLA ANALOG IC DEVICE DATA
CIRCUIT DESCRIPTION
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
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.
NOTE:
* The MC13143 uses a unique and patented circuit topology.
