Infineon Technologies PTF180101S V1

Overview

PTF180101S V1 from Infineon Technologies is a 10 W LDMOS RF power transistor optimized for EDGE, WCDMA, and CW operation in DCS/PCS (1805–1990 MHz) and IMT-2000 (2110–2170 MHz) bands. It delivers 4.0 W average output power at 1989.8 MHz with 19.0 dB gain, 28% drain efficiency, and 1.1% RMS EVM - enabling high-linearity base station final-stage amplification.

For engineers reviewing the PTF180101S V1 datasheet, PTF180101S V1 pinout, PTF180101S V1 application, or PTF180101S V1 equivalent, key selection criteria include its 65 V V(BR)DSS rating, 3.0 °C/W thermal resistance (RθJC), 10:1 VSWR ruggedness at 28 V/10 W CW, and integrated Class 1 HBM ESD protection - critical for outdoor macrocell PA design and broadband repeater systems.

Technical Context

The PTF180101S V1 employs a gold-metallized LDMOS structure with fully matched input/output impedance (Z_Source ≈ 7–8 Ω + j(–2.2 to –4.1) Ω; Z_Load ≈ 4.5–4.6 Ω + j(2.4–2.6) Ω across 1920–2020 MHz), enabling direct integration into microstrip-based reference circuits without external matching networks. Its gate bias operates at V_GS = 2.5–4.0 V under 180 mA quiescent drain current.

It supports multi-standard modulation: EDGE (ACPR –60 dBc @ 400 kHz offset), WCDMA (ACPR –45 dBc, 3GPP TM1 signal), and CW (P_–1dB = 15 W, 50% efficiency). HCI drift is minimized via low-diffusion process design, and thermal stability is ensured by RθJC = 3.0 °C/W at 10 W CW and T_CASE = 70 °C.

Key Specifications

Pinout & Package

PTF180101S V1 is housed in Infineon's 32259 package: a thermally enhanced, surface-mount ceramic/metal flange package with three terminals (Drain, Gate, Source) and integral heat slug for direct PCB thermal coupling. The flange is electrically connected to the Drain terminal.

FAQ

What is the recommended gate bias voltage range for PTF180101S V1 in EDGE mode?

The datasheet specifies V_GS = 2.5–4.0 V at I_DQ = 180 mA and V_DD = 28 V for EDGE operation. Typical bias is 3.2 V, and gate current remains below 1.0 µA. A 220 Ω series resistor (R1/R2/R3 in reference schematic) is used to stabilize bias against thermal drift and prevent oscillation.

Does PTF180101S V1 require external input/output matching networks?

No - the device is internally matched for 50 Ω systems across 1805–1990 MHz and 2110–2170 MHz bands. Reference circuit data (Z_Source ≈ 7–8 Ω, Z_Load ≈ 4.5 Ω) confirms broadband impedance transformation is integrated. Only DC blocking capacitors (C2/C8) and bias chokes are needed per the provided schematic.

What is the maximum continuous drain current rating for PTF180101S V1?

The absolute maximum continuous drain current is not explicitly specified, but the device is rated for 10 W PEP (two-tone) and 15 W P_–1dB CW output. At V_DD = 28 V and η_D = 50%, peak I_D reaches ~1.07 A. The safe operating area (SOA) curve limits pulsed I_D to ≤1.2 A at T_CASE ≤ 70 °C per the thermal derating specification.

Can PTF180101S V1 be used in 5G NR sub-6 GHz applications?

While not characterized for 5G NR waveforms, its 2110–2170 MHz WCDMA performance (–45 dBc ACPR, 1.8 W avg) and 10:1 VSWR ruggedness provide foundational suitability for low-PAPR 5G NR n1/n34/n40 use cases. However, 5G-specific validation (EVM, ACLR at 100 MHz bandwidth) is not documented and requires customer-level characterization.
