Product Description
The RF2461 is a receiver front-end designed for the receive section of dual-mode
CDMA/FM cellular applications. It is designed to amplify and downconvert RF signals, while providing 30dB of stepped gain control range. Features include digital
control of LNA gain, mixer gain, and power down mode. Another feature of the chip
is adjustable IIP3 of the LNA and mixer using an off-chip current setting resistor.
Noise figure, IP3, and gain are designed to be compatible with the IS-98B interim
standard for CDMA cellular communications. The IC is manufactured on an
advanced Silicon Germanium Bi-CMOS process and is assembled in a 4mmx4mm,
20-pin, QFN package.

LNA emitter. This pin provides the DC path to ground for the LNA. A lumped
element or a transmission line inductor can be placed between this pin
and ground to degenerate the LNA. This will decrease the gain and
increase the IP3 of the LNA. As the value of inductance is increased, these
effects will become more pronounced.

An external resistor R2 connected to this pin sets the current of the

An external resistor R3 connected to this pin sets the current of the LNA
when IP SET is high (see pin 19).
Ground pin for preamp circuit. A 3.3nH inductor is used between pin 9 and
ground to degenerate the mixer preamp. Degenerating the preamp will
reduce the gain, increase the IP3 and affect the preamp input impedance.

IP SET
Controls the setting of the LNA current. A logic low (<1.0V) selects the
internal resistance (49.5kΩ), resulting in an LNA current of 5mA. A logic

IF SEL
Determines which IF port is active. A logic low (<1.0V) activates IF1 and
deactivates IF2. A logic high (>2.0V) activates IF2 and deactivates IF1.

L1, C1, and R form a current combiner which performs a differential to single-ended conversion at the IF frequency and sets
the output impedance. In most cases, the resonance frequency is independent of R and can be set according to the following
equation:
Where CEQ is the equivalent stray capacitance and capac1
fIF =
itance
looking into pins 11 and 12. An average value to
L1
(C1 + CEQ)
2π
2
use for CEQ is 2.5pF to 3pF.
R can then be used to set the output impedance according to the following equation:
L2 and C2 serve dual purposes. L2 serves as an output
1
R = (
- 1 ) -1
bias choke, and C2 serves as a series DC block.
4 R OU T
RP
where ROUT is the desired output impedance and RP is the
parasitic equivalent parallel resistance of L1.
C1 should be chosen as high as possible (not greater
than 15pF), while maintaining an RP of L1 that allows for
the desired ROUT.
8 of 14
In addition, L2 and C2 may be chosen to form an impedance matching network if the input impedance of the IF
filter is not equal to ROUT. Otherwise, L2 is chosen to be
large, and C2 is chosen to be large if a DC path to ground
is present in the IF filter, or omitted if the filter is DC
blocked.
