RF2046
GENERAL PURPOSE AMPLIFIER
Typical Applications
• Broadband, Low Noise Gain Blocks
• IF or RF Buffer Amplifiers
• Driver Stage for Power Amplifiers
• Final PA for Low Power Applications
• High Reliability Applications
• Broadband Test Equipment
Product Description
The RF2046 is a general purpose, low cost RF amplifier
IC. The device is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as an easily-cas-
cadable 50gain block. Applications include IF and RF
amplification in wireless voice and data communication
products operating in frequency bands up to 3000MHz.
The device is self-contained with 50input and output
impedances and requires only two external DC biasing
elements to operate as specified. With a goal of
enhanced reliability, the extremely small Micro-X ceramic
package offers significantly lower thermal resistance than
similar size plastic packages.

Pin Function Description
Interface Schematic
1
RF IN
RF input pin. This pin is NOT internally DC blocked. A DC blocking
capacitor, suitable for the frequency of operation, should be used in
most applications. DC coupling of the input is not allowed, because this
will override the internal feedback loop and cause temperature instabil-
ity.
2
GND
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
3 RF OUT RF output and bias pin. Biasing is accomplished with an external series
resistor and choke inductor to VCC. The resistor is selected to set the
DC current into this pin to a desired level. The resistor value is deter-
mined by the following equation:
R = (---V----S--U----P---P----L---Y----–----V----D----E---V---I--C----E---)
ICC
RF IN
RF OUT
Care should also be taken in the resistor selection to ensure that the
current into the part never exceeds 75 mA over the planned oper-
ating temperature. This means that a resistor between the supply and
this pin is always required, even if a supply near 3.6V is available, to
provide DC feedback to prevent thermal runaway. Because DC is
present on this pin, a DC blocking capacitor, suitable for the frequency
of operation, should be used in most applications. The supply side of
the bias network should also be well bypassed.
