Product Description
The RF2627 is a complete AGC amplifier designed for
the receive section of 3V CDMA cellular and PCS appli-
cations. It is designed to amplify IF signals while provid-
ing more than 90dB of gain control range. Noise Figure,
IP3, and other specifications are designed for CDMA
handsets. This circuit is designed as part of the RFMD
CDMA Chip Set, consisting of a Transmit IF AGC Amp, a
Transmit Upconverter, a Receive LNA/Mixer, and this
Receive IF AGC Amp. The IC is manufactured on an
advanced high frequency Silicon Bipolar process, and is
packaged in a standard miniature 8-lead plastic MSOP
package.

Description
CDMA Balanced Input Pin. This pin is internally DC biased and should
be DC blocked if connected to a device with a DC level other than VCC
present. A DC to connection to VCC is acceptable. For single-ended
input operation, one pin is used as an input and the other CDMA input
is AC coupled to ground. The balanced input impedance is 1k, while
the single-ended input impedance is 500.

Same as pin 2, except complementary input.
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
Analog gain adjustment for all amplifiers. Valid control ranges are from
0V to 3.0V. Maximum gain is selected with 3.0V. Minimum gain is
selected with 0V. These voltages are only valid for a 4.7kDC source
impedance.

OUT-
Balanced Output pin. This is an open-collector output, designed to
operate into a 250balanced load. The load sets the operating imped-
ance, but an external choke or matching inductor to VCC must also be
OUT+
OUT-
supplied in order to correctly bias this output. This bias inductor is typi-
cally incorporated in the matching network between the output and next
stage. Because this pin is biased to VCC, a DC blocking capacitor must
be used if the next stage’s input has a DC path to ground.

OUT+
Same as pin 5, except complementary output.
See pin 5.

VCC1
Supply Voltage pin. External bypassing is required. The trace length
between the pin and the bypass capacitors should be minimized. The
ground side of the bypass capacitors should connect immediately to
ground plane.

VCC2
Same as pin 7.
