Diodes Incorporated ZAMP001H6TA

Overview

ZAMP001H6TA from Zetex (now Diodes Incorporated) is a monolithic microwave integrated circuit (MMIC) low-noise amplifier optimized for L-band and IF applications, including satellite LNB receivers and TV tuners. It delivers 18 dB typical gain, 5 dB noise figure at 1 GHz, +8 dBm IP3 at 1 GHz, operates from 4.5–5.5 V, and draws only 12.2 mA typical supply current.

For engineers reviewing the ZAMP001H6TA datasheet, ZAMP001H6TA pinout, ZAMP001H6TA application, or ZAMP001H6TA equivalent, this RFIC provides verified wideband performance from 800 MHz to 2500 MHz with rising gain compensation, unconditional stability, and 50 Ω input/output impedance-enabling direct integration without external matching networks.

Technical Context

The ZAMP001H6TA employs a GaAs-based MMIC architecture with internal biasing optimized for single-supply operation at 5 V. Its rising gain profile (17 dB @ 950 MHz → 20 dB @ 2150 MHz) actively compensates for frequency-dependent loss in front-end receiver chains.

It achieves unconditional stability across its full 800–2500 MHz operating band without external stabilization components, and integrates matched 50 Ω input/output ports-eliminating need for external matching inboard of DC-blocking capacitors.

Key Specifications

Pinout & Package

Package: SC70-6 surface-mount package (1.00 × 2.00 mm footprint, 0.90 mm max height), optimized for high-frequency layout with short internal bond wires and symmetric ground pins.

Equivalent & Alternatives

The following parts are listed as comparable options for similar wideband LNA applications.

Compared with QPL9057 and SKY67153-396LF, the ZAMP001H6TA uniquely balances ultra-low current (12.2 mA), rising gain, and 5 V operation-making it the optimal choice for cost-sensitive, thermally constrained DBS LNBs where 800–2500 MHz coverage and 50 Ω simplicity are mandatory.

Availability

ZAMP001H6TA is available at Aetrix Electronics and suitable for satellite LNB receivers, TV tuners, and SMR radios requiring stable component supply, consistent RF performance across temperature, and long-term obsolescence mitigation.

Supply support for ZAMP001H6TA includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Zetex Semiconductors (acquired by Diodes Incorporated in 2008) specialized in high-performance analog and RF solutions for consumer, communications, and industrial markets.

The ZAMP series was developed specifically for low-noise, low-current wideband RF amplification in satellite and broadcast receiver front-ends-prioritizing 50 Ω integration, thermal efficiency, and production-ready layout simplicity.

FAQ

What is the recommended DC-blocking capacitor value for ZAMP001H6TA input and output?

A 100 pF NPO ceramic capacitor is specified for 950–2150 MHz operation, providing <0.33 Ω reactance at 950 MHz-well below 50 Ω to preserve impedance match. For lower frequencies, increase capacitance to maintain Xc < 5 Ω at the lowest operating frequency.

Is external matching required for 50 Ω system integration?

No external matching is required. The ZAMP001H6TA features fully integrated 50 Ω input and output impedance-verified across 800–2500 MHz. Only DC-blocking capacitors and local VCC decoupling (100 pF NPO + 100 nF X7R) are needed per the reference layout.

Can ZAMP001H6TA operate from a 3.3 V supply?

No. Absolute maximum rating is 7 V, but the device is characterized and optimized for 4.5–5.5 V operation. At 3.3 V, gain drops >6 dB, NF degrades >3 dB, and IP3 falls below –5 dBm-rendering it nonfunctional for specified applications.

What is the thermal resistance (θ_JA) of the SC70-6 package?

The SC70-6 package has a measured θ_JA of 220°C/W under standard JEDEC 2-layer board conditions. With 12.2 mA at 5 V (61 mW dissipation), junction temperature rise is ~13.4°C above ambient-enabling operation up to +85°C ambient without derating.
