Diodes Incorporated ZAMP001H6TC

Overview

ZAMP001H6TC from Zetex Semiconductors is a monolithic microwave integrated circuit (MMIC) low-noise amplifier optimized for L-band and IF applications, operating from 800 MHz to 2500 MHz with 18 dB typical gain, 5 dB noise figure at 950 MHz, and 8 dBm IP3 at 2150 MHz. It delivers stable 50 Ω input/output impedance, rising gain profile, and operates from 4.5–5.5 V at 12.2 mA typical supply current.

For engineers reviewing the ZAMP001H6TC datasheet, ZAMP001H6TC pinout, ZAMP001H6TC application, or ZAMP001H6TC equivalent, key selection criteria include its wideband LNA performance in satellite LNB front-ends, low-current operation in space-constrained tuners, and unconditional stability without external matching networks.

Technical Context

The ZAMP001H6TC employs a GaAs-based MMIC architecture with internal biasing and no RF matching components required. Its rising gain slope (17 dB at 950 MHz → 20 dB at 2150 MHz) compensates for interconnect and filter losses at higher frequencies in DBS signal chains.

It achieves unconditional stability across 800–2500 MHz via on-die stabilization networks, enabling direct integration into 50 Ω systems. Input/output return loss exceeds 9 dB (input) and 12 dB (output) across band, supporting broadband cascade design without external tuning.

Key Specifications

Pinout & Package

SC70-6 surface-mount package (1.00 × 2.00 mm footprint, 0.90 mm height), lead-free, RoHS-compliant, with exposed thermal pad (not electrically connected).

Key Features

Applications

Equivalent & Alternatives

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

Compared with QPL9547 and ERA-5SM+, the ZAMP001H6TC uniquely balances sub-6 dB NF, rising gain, and <13 mA consumption in a matchless SC70-6 package - making it optimal for cost-sensitive, space-limited DBS and tuner applications where simplicity and thermal efficiency are prioritized over absolute NF or P1dB.

FAQ

Does ZAMP001H6TC require external matching components?

No. The ZAMP001H6TC features fully integrated 50 Ω input and output matching networks. Only two external 100 pF DC-blocking capacitors (on input and output) and one 100 pF NPO supply decoupling capacitor (on VCC) are required per the datasheet test circuit. No inductors, resistors, or transmission-line matching elements are needed.

What is the maximum safe operating voltage for ZAMP001H6TC?

The absolute maximum supply voltage is 7 V, but the device is characterized and guaranteed for stable operation only between 4.5 V and 5.5 V. Operation above 5.5 V may cause increased current draw, degraded noise figure, or accelerated aging. For reliable long-term performance, maintain VCC within the 4.5–5.5 V range.

Can ZAMP001H6TC operate at -40°C ambient temperature?

Yes. The ZAMP001H6TC is fully specified and tested from -40°C to +85°C ambient. Electrical parameters including gain, noise figure, and IP3 remain within datasheet limits across this range. Its unconditional stability and internal biasing ensure robust cold-start behavior in outdoor satellite equipment.

Is the SC70-6 package of ZAMP001H6TC lead-free and RoHS compliant?

Yes. The ZAMP001H6TC uses a lead-free, RoHS-compliant SC70-6 package with matte tin-plated leads. The device meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level (MSL) 1 rating, allowing unlimited floor life at ≤30°C/60% RH.
