Product Description
The NBB-400 cascadable broadband InGaP/GaAs MMIC amplifier is a
low-cost, high-performance solution for general purpose RF and micro-
wave amplification needs. This 50Ω gain block is based on a reliable HBT
proprietary MMIC design, providing unsurpassed performance for small-
signal applications. Designed with an external bias resistor, the NBB-400
provides flexibility and stability. The NBB-400 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 packaged or chip
(NBB-400-D) form, where its gold metallization is ideal for hybrid circuit
designs.

Function
RF IN
Description
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.
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
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
5.0V 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.

Sales Criteria - Unpackaged Die
Die Sales Information
• All segmented die are sold 100% DC-tested. Testing parameters for wafer-level sales of die material shall be nego-
tiated on a case-by-case basis.
• Segmented die are selected for customer shipment in accordance with RFMD Document #6000152 - Die Product
Final Visual Inspection Criteria
1
.
• Segmented die has a minimum sales volume of 100 pieces per order. A maximum of 400 die per carrier is allow-
able.
Die Packaging
• All die are packaged in GelPak ESD protective containers with the following specification:
O.D.=2"X2", Capacity=400 Die (20X20 segments), Retention Level=High(X0).
• GelPak ESD protective containers are placed in a static shield bag. RFMD recommends that once the bag is
opened the GelPak/s should be stored in a controlled nitrogen environment. Do not press on the cover of a closed
GelPak, handle by the edges only. Do not vacuum seal bags containing GelPak containers.
• Precaution must be taken to minimize vibration of packaging during handling, as die can shift during transit
2
.
Package Storage
• Unit packages should be kept in a dry nitrogen environment for optimal assembly, performance, and reliability.
• Precaution must be taken to minimize vibration of packaging during handling, as die can shift during transit
2
.
Die Handling
• Proper ESD precautions must be taken when handling die material.
• Die should be handled using vacuum pick-up equipment, or handled along the long side with a sharp pair of twee-
zers. Do not touch die with any part of the body.
• When using automated pick-up and placement equipment, ensure that force impact is set correctly. Excessive force
may damage GaAs devices.
