Infineon Technologies BAT15-098LRHE6327

Overview

BAT15-098LRHE6327 from Infineon Technologies is a silicon Schottky diode optimized for DBS mixer applications up to 12 GHz, phase detectors, and RF modulators. It features low barrier height, 0.4 nH series inductance, 0.35–0.5 pF capacitance at 0 V/1 MHz, and 5.5 Ω typical differential forward resistance at 10 mA, enabling high-frequency signal detection in satellite receiver front-ends.

For engineers reviewing the BAT15-098LRHE6327 datasheet, BAT15-098LRHE6327 pinout, BAT15-098LRHE6327 application, or BAT15-098LRHE6327 equivalent, key selection criteria include RF capacitance matching, low-noise figure performance, thermal resistance (≤780 K/W), and TSLP-4-7 leadless anti-parallel pair configuration for balanced mixer topologies.

Technical Context

This device is configured as an anti-parallel pair in a single TSLP-4-7 leadless package, supporting balanced RF signal processing without external pairing. Its low 0.4 nH LS and sub-0.5 pF CT at 0 V enable stable impedance matching above 10 GHz.

The diode operates with VF = 0.23–0.41 V (IF = 10 mA), IR < 10 µA at VR = 2 V, and maintains junction temperature ≤150 °C under Ptot = 100 mW - critical for continuous-wave operation in compact LNB modules.

Key Specifications

Pinout & Package

TSLP-4-7 is a 4-terminal, leadless, surface-mount package with exposed thermal pad; dimensions 1.3 × 0.8 × 0.35 mm. The anti-parallel pair shares no common terminal - terminals are fully isolated for differential RF routing.

FAQ

What is the maximum recommended RF input power for BAT15-098LRHE6327 in mixer applications?

The device supports peak RF input power up to +10 dBm in pulsed operation (tp ≤ 10 µs, D = 0), but continuous-wave operation should be limited to ≤+7 dBm to maintain junction temperature below 150 °C given its 100 mW Ptot rating and 780 K/W RthJS. Derating is required above 85 °C ambient.

Does BAT15-098LRHE6327 require DC bias for operation in mixer circuits?

No DC bias is required - the BAT15-098LRHE6327 functions as a zero-bias Schottky detector/mixer. Its low barrier height (VF ≈ 0.23 V at 10 mA) enables efficient nonlinear RF-to-IF conversion without external bias networks, simplifying LNB front-end design and reducing power consumption.

How does the TSLP-4-7 package affect PCB layout for 12 GHz designs?

The TSLP-4-7's 0.4 mm pin pitch and integrated thermal pad demand controlled-impedance microstrip routing with ≤0.1 mm trace width tolerance. Ground vias must be placed within 0.3 mm of each cathode pad to minimize loop inductance - critical to preserve the specified 0.4 nH LS and avoid resonance above 10 GHz.

Is BAT15-098LRHE6327 suitable for use in automotive radar modules?

While rated for −55 °C to +150 °C operation, BAT15-098LRHE6327 is not AEC-Q200 qualified and lacks automotive-specific reliability testing (e.g., vibration, HTOL). It is widely used in industrial and consumer 12 GHz systems, but automotive radar designs require components with formal automotive qualification and PPAP documentation.
