Portable Battery-Powered Equipment
The RF2890 is a high performance dual band CDMA Cel-
lular and GPS LNA/mixer. An integrated optional LO pres-
caler allows VCO flexibility. The device is designed to
exceed all sensitivity, intermodulation and single-tone
requirements. The RF2890 is designed for three state
gain control solutions (17.5dB of gain control) for cellular
band IMD testing. The device offers a dedicated low cur-
rent (15.5mA) GPS LNA/mixer with 32.5dB gain. An inte-
grated TX LO buffer is also included. The design is
flexible, in that the bias currents may be set using off-chip
current reference resistors for the mixer and LNA blocks.
Noise figure, IIP3, and other specifications are designed
to be compatible with the TIA/EIA 98D standard for
CDMA cellular communications. The device is packaged
in a plastic, 4mmx4mm QFN.

IF Output Interface Network
Single-End IF Matching
L1, C1, C2, 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 C
EQ
is the equivalent stray capacitance and capacitance looking into pins 9 and 10. An average value to use for
C
EQ
is 2.5pF.
R can then be used to set the output impedance according to the following equation:
where R
OUT
is the desired output impedance and R
P
is the parasitic equivalent parallel resistance of L1.
C
2
should first be set to 0 and C1 should be chosen as high as possible (not greater than 39pF), while maintaining an R
P
of L1 that allows for the desired R
OUT
. If the self-resonant frequencies of the selected C1 produce unsatisfactory linearity
performance, their values may be reduced and compensated for by including C2 capacitor with a value chosen to main-
tain the desired F
IF
frequency.
L2 and C3 serve dual purposes. L2 serves as an output bias choke, and C3 serves as a series DC block.
In addition, L2 and C3 may be chosen to form an impedance matching network if the input impedance of the IF filter is
not equal to R
OUT
. Otherwise, L2 is chosen to be large (suggested 120nH) and C3 is chosen to be large (suggested
22nF) if a DC path to ground is present in the IF filter, or omitted if the filter is DC-blocked.

Differential IF Matching
L1 and C1 are chosen to resonate at the desired IF frequency. C1 can be omitted and the value of L1 increased and uti-
lized solely as a choke to provide V
CC
to the open-collector outputs, but it is strongly recommended that at least some
small-valued C1 (a few pF) be retained for better mixer linearity performance. R is normally selected to match the input
impedance of the IF filter. However, mixer performance can be modified by selecting an R value that is different from the
IF filter input impedance, and inserting a conjugate matching network between the Resistive Output Network and the IF
filter.
C2 serve dual purposes. C2 serves as a series DC block when a DC path to ground is present in the IF filter. In addition,
C2 may be chosen to improve the combine performance of the mixer and IF filter. L2 should choose to resonate with the
internal capacitance of the SAW filter. Usually, SAW filter has some capacitance. Otherwise, L2 could be eliminated.
A practical approach to obtain the differential matching is to tune the mixer to the correct load point for gain, IIP3, and NF
using the single-end current combiner method. Second, use the component values found in the single-end approach as
starting point for the differential matching. The two-shunt capacitors in the single-end could be converted in a parallel
capacitor and the parallel inductor in the single-end need to be converted in two-choke inductor. Third, set the DC block
capacitors (C2) in the differential-end matching to a high value (i.e., 100pF) and retune the resonate circuit (C1 & L1)
and the resistor (R) for optimal performance. After optimal performance is achieved and if performance is not satisfac-
tory, decrease the series capacitors until optimal performance is achieved.

PCB Design Requirements
PCB Surface Finish
The PCB surface finish used for RFMD's qualification process is electroless nickel, immersion gold. Typical thickness is
3
inch to 8
inch gold over 180
inch nickel.
PCB Land Pattern Recommendation
PCB land patterns are based on IPC-SM-782 standards when possible. The pad pattern shown has been developed and
tested for optimized assembly at RFMD; however, it may require some modifications to address company specific
assembly processes. The PCB land pattern has been developed to accommodate lead and package tolerances.
