Infineon Technologies BAT 15-099LRH E6327

Overview

BAT15-099LRH from Infineon Technologies is a silicon Schottky diode configured as an anti-parallel pair in a leadless TSLP-4-7 package, optimized for DBS mixer applications up to 12 GHz, phase detection, and RF modulation. It features 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.

For engineers reviewing the BAT15-099LRH datasheet, BAT15-099LRH pinout, BAT15-099LRH application, or BAT15-099LRH equivalent, key selection criteria include RF matching performance in high-frequency mixers, low-noise figure operation below 12 GHz, thermal resistance (RthJS ≤ 780 K/W), and anti-parallel configuration for balanced signal handling.

Technical Context

This diode pair leverages low-barrier silicon Schottky junctions to minimize noise figure and enable broadband operation from DC to 12 GHz. Its anti-parallel configuration supports symmetrical RF signal routing in double-balanced mixers and phase detectors.

The TSLP-4-7 leadless package delivers low parasitic inductance (0.4 nH) and controlled capacitance (0.35–0.5 pF), critical for maintaining impedance integrity in 50 Ω RF paths. Thermal resistance of ≤780 K/W enables stable operation at junction temperatures up to 150 °C under pulsed or continuous bias.

FAQ

What is the maximum recommended RF input power for BAT15-099LRH in mixer applications?

The device is rated for 100 mW total power dissipation. At 11 GHz with typical 5.5 Ω RF and 0.35 pF CT, peak RF input power should be limited to ≤+13 dBm (20 mW) for continuous operation to maintain junction temperature below 150 °C. Pulsed operation allows brief excursions to +20 dBm with duty cycle ≤1%.

Does BAT15-099LRH require DC bias for operation in mixer circuits?

No DC bias is required - it operates as a passive switching element in double-balanced mixers. The anti-parallel configuration enables self-biased operation using the local oscillator signal. However, a small DC blocking capacitor (e.g., 100 pF) is recommended on each RF port to prevent LO leakage into baseband circuitry.

How does the TSLP-4-7 package affect RF layout compared to SOT-323 or SOT-143?

TSLP-4-7's symmetric 4-pin leadless design minimizes bond wire inductance and provides dedicated ground-return paths via the exposed pad. Unlike SOT-323 (2-pin) or SOT-143 (4-pin with internal common cathode), TSLP-4-7 enables true anti-parallel routing with matched trace lengths and identical parasitics on both branches - critical for >8 GHz balance.

Is BAT15-099LRH suitable for 5G FR2 (24–40 GHz) applications?

No - its specified performance is validated up to 12 GHz. Above 15 GHz, measured CT and LS cause increasing mismatch and insertion loss; measured S21 roll-off exceeds 3 dB at 14 GHz. For mmWave, Infineon's BAP70-03 or Skyworks SMS7630 are characterized through 40 GHz.
