Package Drawing
Pin Function Description Interface Schematic
1RF 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 applica-
tions. DC coupling of the input is not allowed, because this will override the
internal feedback loop and cause temperature instability.
2GND
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
3RF 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 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.
4GND
Same as pin 2.

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 Criteria1.
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 protec tive containers with the follow ing 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 nitrog en environment. Do not press on the cover of a closed
GelPak, handle by the edges only. Do no t vac uum seal bags containing GelPak containers.
Precaution mus t be taken to minimize vibration of packag in g duri n g ha nd lin g, as die can shift duri n g transit 2.
Package Storage
Unit packages should be kept in a dry nitrogen environment for optimal assembly, performance, and reliability.
Precaution mus t be taken to minimize vibration of packag in g duri n g ha nd lin g, as die can shift duri n g transit2.
Die Handling
Proper ESD precautions must be taken when handling die material.
Die should be handled using vacuum pick-up equipment, or handled al ong 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 devic es .

Die Attach
The die attach process mechanically attaches the die to the circuit substrate. In addition, the utilization of proper die
attach processes electrically connect the ground to the trace on which the chip is mounted. It also establishes the
thermal path by which heat can leave the chip.
Die should be mounted to a clean, flat surfac e. Epox y or eutectic die attach are both acceptable attachment meth-
ods. Top and bottom metallization are gold. Conductive silver-filled epoxies are recommended. This procedure
involves the use o f ep ox y to form a joint between the backside gold of the chip and the metallized area of the sub-
strate.
All connections should be made on the topside of the die. It is essential to performance that the backside be well
grounded and tha t the length of topside interconnects be minimized.
Some die utilize vias for effective grounding. Care must be exercised when mounting die to preclude excess run-out
on the topside.
Die Wire Bonding
Electrical conne ctions to the chip are made through wire bonds. Either wedge or ball bonding methods are accept-
able practices for wire bonding.
All bond wires should be made as short as possible.
Notes
1RFMD Document #6000152 - Die Product Final Visual Inspection Criteria. This document provides guidance for die inspec-
tion personnel to determine final visual acceptance of die product prior to shipping to customers.
2RFMD takes precautions to ensure that die product is shipped in accordance with quality standards established to minimize
material shift. However, due to the physical size of die-level product, RFMD does not guarantee that material will not shift dur-
ing transit, especially under extreme handling circumstances. Product replacement due to material shift will be at the discre-
tion of RFMD.

Tape and Reel Dimensions
All Dimensions in Millimeters
Carrier tape basic dimensions are based on EIA 481. The pocket is designed to hold the part for shipping and loading onto SMT
manufacturing equipment, while protecting the body and the solder terminals from damaging stresses. The individual pocket
design can vary from vendor to vendor, but width and pitch will be consistent.
Carrier tape is wound or placed onto a shipping reel 178 mm (7 inches) in diameter. The center hub design is large enough to
ensure the radius formed by the carrier tape around it does not put unnecessary stress on the parts.
Prior to shipping, moisture sensitive parts (MSL Level 2a-5a) are baked and placed into the pockets of the carrier tape. A cover
tape is sealed over the top of the entire length of the carrier tape. The reel is sealed in a moisture barrier ESD bag with the
appropriate units of desiccant and a humidity indicator card, which is placed in a cardboard shipping box. It is important to
note that unused moisture sensitive parts need to be resealed in the moisture barrier bag. If the reels exceed the exposure
limit and need to be rebaked, most carrier tape and shipping reels are not rated as bakeable at 125°C. If baking is required,
devices may be baked according to section 4, table 4-1, column 8 of Joint Industry Standard IPC/JEDEC J-STD-033.
Table 1 provides useful information for carrier tape and reels used for shipping the devices described in this document.
