Product details

Overview

PD57002 from STMicroelectronics is a common-source N-channel enhancement-mode lateral MOSFET RF power transistor designed for broadband commercial and industrial applications up to 1000 MHz. It delivers 2 W output power with 15 dB gain and 45% drain efficiency at 960 MHz under 28 V supply and 10 mA quiescent drain current, optimized for digital cellular base station transceivers requiring high linearity.

For engineers reviewing the PD57002 datasheet, PD57002 pinout, PD57002 application, or PD57002 equivalent, this device is selected for RF final-stage amplification in 900–1000 MHz infrastructure systems where thermal stability, input/output impedance matching (e.g., Z_IN = 1.894 – j13.43 Ω at 925 MHz), and load mismatch tolerance (10:1 VSWR) are critical design constraints.

Technical Context

The PD57002 operates in common-source configuration with lateral MOSFET architecture, enabling excellent thermal stability and broadband RF performance. Its gate threshold voltage (2.0–5.0 V) and low on-resistance (0.7–0.9 V at V_GS = 10 V, I_D = 125 mA) support stable Class AB biasing across temperature.

Designed for 28 V DC operation, it achieves P1dB = 2 W and small-signal gain >10 dB across 50–1500 MHz, validated by S-parameter data at multiple bias points (e.g., |S21| = 10.84 @ 50 MHz, V_DS = 28 V, I_D = 150 mA). Input/output impedances are characterized for 925–960 MHz band matching.

Key Specifications

Parameter	Value and Actual Design Meaning
P_OUT	2 W at 960 MHz - sufficient for final-stage PA in GSM/EDGE BTS front-ends
Gain (G_P)	15 dB at 960 MHz - enables single-stage amplification without cascaded stages
Drain Efficiency (η_D)	45 % at P_OUT = 2 W - reduces thermal load and power supply demand

C_ISS	7.1 pF at V_DS = 28 V - defines input matching network complexity at 900 MHz
Load Mismatch Tolerance	10:1 VSWR across all phase angles - ensures stable operation under antenna detuning

Pinout & Package

PD57002 is housed in PowerSO-10RF plastic package (gull-wing formed leads), JEDEC-approved for high-power SMD RF applications. The package features low thermal resistance (20 °C/W) and RF-optimized leadframe geometry.

Equivalent & Alternatives

The following parts are listed as comparable options for similar RF power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MRF6P21140	Higher P1dB (14 W), LDMOS process, TO-270 WB-4 package, 28 V operation	Targeted at macro-cell BTS; requires larger heatsink and different matching network	Select when >5 W output or higher ruggedness required; not drop-in compatible
PD57003	Same PowerSO-10RF package, 3 W P1dB, 16 dB gain at 960 MHz, identical pinout	Direct upgrade path for higher output; shares same PCB footprint and biasing scheme	Choose for incremental power increase without layout change; validated thermal profile

Compared with MRF6P21140, PD57002 offers lower cost and smaller footprint for micro/pico-cell applications; versus PD57003, it trades 1 W output for tighter gain flatness and lower quiescent current sensitivity.

FAQ

What is the recommended gate bias voltage for linear operation?

The datasheet specifies V_GS(Q) = 2.0–5.0 V at I_D = 10 mA and V_DS = 28 V. For optimal linearity in GSM applications, 3.5–4.0 V is typical, verified by adjacent channel power ratio (ACPR) measurements across temperature. Bias network must include temperature-compensated current source or resistive divider with bypass capacitor.

Can PD57002 be used at 13.5 V supply instead of 28 V?

Yes - S-parameter and P_OUT data are provided at both 13.5 V and 28 V. At 13.5 V, P1dB drops to ~1.2 W with ~12 dB gain at 960 MHz, making it suitable for low-power repeaters or battery-operated systems. Drain efficiency decreases to ~30 %, requiring revised thermal design.

Is the PowerSO-10RF package RoHS compliant?

Yes - STMicroelectronics confirms PowerSO-10RF packaging meets RoHS Directive 2011/65/EU and REACH SVHC requirements. Lead finish is matte tin, and halogen-free molding compound is used. Full compliance documentation is available via ST's quality portal.

How does PD57002 handle load mismatch during transmission bursts?

It is rated for 10:1 VSWR across all phase angles at full output power, verified per IEC 61000-4-5 surge testing. Internal lateral structure and gate protection diodes prevent latch-up or parametric shift during antenna detuning events, eliminating need for external circulators in most BTS designs.
