Product Description
The NBB-312 cascadable broadband InGaP/GaAs MMIC amplifier is a low-
cost, high-performance solution for general purpose RF and microwave
amplification needs. This 50Ω gain block is based on a reliable HBT pro-
prietary MMIC design, providing unsurpassed performance for small-sig-
nal applications. Designed with an external bias resistor, the NBB-312
provides flexibility and stability. The NBB-310 is packaged in a low-cost,
surface-mount ceramic package, providing ease of assembly for high-vol-
ume tape-and-reel requirements. It is available in either 1,000 or 3,000
piece-per-reel quantities. Connectorized evaluation board designs opti-
mized for high frequency are also available for characterization purposes.

Description
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
Same as pin 1.
Same as pin 1.
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 applica-
tions. DC coupling of the input is not allowed, because this will override the
internal feedback loop and cause temperature instability.

RF output and bias pin. Biasing is accomplished with an external series
resistor and choke inductor to V
CC
. The resistor is selected to set the DC
current into this pin to a desired level. The resistor value is determined by
the following equation:

Care should also be taken in the resistor selection to ensure that the cur-
rent into the part never exceeds maximum datasheet operating current
over the planned operating temperature. This means that a resistor
between the supply and this pin is always required, even if a supply near
8.0V is available, to provide DC feedback to prevent thermal runaway.
Alternatively, a constant current supply circuit may be implemented.
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.
