ATF-34143 Low Noise Pseudomorphic HEMT in a Surface Mount Plastic Package Data Sheet Description Features Avago’s ATF-34143 is a high dynamic range, low noise PHEMT housed in a 4-lead SC-70 (SOT-343) surface mount plastic package. Lead-free Option Available Based on its featured performance, ATF-34143 is ideal for the first stage of base station LNA due to the excellent combination of low noise figure and high linearity[1]. The device is also suitable for applications in Wireless LAN, WLL/RLL, MMDS, and other systems requiring super low noise figure with good intercept in the 450 MHz to 10 GHz frequency range. 800 micron Gate Width Note: 1.9 GHz; 4V, 60 mA (Typ.) 1. From the same PHEMT FET family, the larger geometry ATF-33143 may also be considered either for the higher linearity performance or easier circuit design for stability in the lower frequency bands (800– 900 MHz).

Measurements made on a fixed toned production test board that was tuned for optimal gain match with reasonable noise figure at 4V, 60 mA bias. This circuit represents a trade-off between optimal noise match, maximum gain match, and a realizable match based on production test board requirements. Circuit losses have been de-embedded from actual measurements. 2. P1dB measurements are performed with passive biasing. Quicescent drain current, IDSQ, is set with zero RF drive applied. As P1dB is approached, the drain current may increase or decrease depending on frequency and dc bias point. At lower values of IDSQ the device is running closer to class B as power output approaches P1dB. This results in higher PAE (power added efficiency) when compared to a device that is driven by a constant current source as is typically done with active biasing. As an example, at a VDS = 4 V and IDSQ = 10 mA, Id increases to 62 mA as a P1dB of +19 dBm is approached. 4 ATF-34143 Typical Performance Curves, continued 33 35 31 30 1.0 Ga (dB) NF (dB) 20 15 0.5 P1dB, OIP3 (dBm) 29 OIP3 27 85 C 25 C -40 C 25 23 P1dB 21 10 0 2000 4000 0 8000 6000 2.0 1.5 10 8000 1.0 0.5 0 20 40 60 80 100 120 140 0 Figure 16.

Refer to the noise parameter application section for more information. 2. S and noise parameters are measured on a microstrip line made on 0.025 inch thick alumina carrier. The input reference plane is at the end of the gate lead. The output reference plane is at the end of the drain lead. The parameters include the effect of four plated through via holes connecting source landing pads on top of the test carrier to the microstrip ground plane on the bottom side of the carrier.

The Fmin values are based on a set of 16 noise figure measurements made at 16 different impedances using an ATN NP5 test system. From these measurements, a true Fmin is calculated. Fmin represents the true minimum noise figure of the device when the device is presented with an impedance matching network that transforms the source impedance, typically 50Ω, to an impedance represented by the reflection coefficient o. The designer must design a matching network that will present o to the device with minimal associated circuit losses. The noise figure of the completed amplifier is equal to the noise figure of the device plus the losses of the matching network preceding the device. The noise figure of the device is equal to Fmin only when the device is presented with o. If the reflection coefficient of the matching network is other than o, then the noise figure of the device will be greater than Fmin based on the following equation. NF = Fmin + 4 Rn |s – o | 2 Zo (|1 + o| 2)(1 –s| 2) Where Rn /Zo is the normalized noise resistance, o is the optimum reflection coefficient required to produce Fmin and s is the reflection coefficient of the source impedance actually presented to the device. The losses of the matching networks are non-zero and they will also add 11 to the noise figure of the device creating a higher amplifier noise figure. The losses of the matching networks are related to the Q of the components and associated printed circuit board loss. o is typically fairly low at higher frequencies and increases as frequency is lowered. Larger gate width devices will typically have a lower o as compared to narrower gate width devices. Typically for FETs, the higher o usually infers that an impedance much higher than 50Ω is required for the device to produce Fmin. At VHF frequencies and even lower L Band frequencies, the required impedance can be in the vicinity of several thousand ohms. Matching to such a high impedance requires very hi-Q components in order to minimize circuit losses. As an example at 900 MHz, when airwwound coils (Q > 100) are used for matching networks, the loss can still be up to 0.25 dB which will add directly to the noise figure of the device. Using muiltilayer molded inductors with Qs in the 30 to 50 range results in additional loss over the airwound coil. Losses as high as 0.5 dB or greater add to the typical 0.15 dB Fmin of the device creating an amplifier noise figure of nearly 0.65 dB. A discussion concerning calculated and measured circuit losses and their effect on amplifier noise figure is covered in Avago Application 1085.
